Title: Nano-structured polymeric/hybrid materials
09:20-09:55
Biography
Abstract
In the first part, a summary of the design, the assembly, and the structural and functional characterization of nanostructured materials using anodized aluminum oxide (AAO) as a template is described. A particularly powerful analytical tool is optical waveguide spectroscopy using the nanoporous template as the guiding structure. It is demonstrated that this format allows for a very sensitive label-free detection of analytes of low molecular mass. Other strategies for using the AAO layers as templates include the growth of polymeric nano-rod arrays from different functional monomers which after the dissolution of the template are still able to guide light. This opens up novel concepts for integrated optics platforms with nanostructured materials. In the second part, we introduce an electronic transducer principle based on graphene field effect transistors that allow us to monitor enzymatic activities of multilayer assemblies by this novel analytical approach.

Abstract
Metallic nanowires, due to their plasmonic character combined with the ability to efficiently transport excitations, are highly suitable for controlling the optical properties of other nanostructures, such as polymers, nanocrystals or biomolecules. Importantly, while diameters of such nanowires, in the range of 100 nm, are small enough to exhibit plasmonic effects in the broad spectral range, their lengths exceeding tens of micrometers make them visible using standard microscopy. In addition, by functionalizing their surface, it is possible to tailor their biochemical function, for instance as sensors. In the talk, we will discuss selected experiments carried out using silver nanowires as building blocks of hybrid nanostructures. The first result was obtained by attaching photosynthetic pigmentprotein complexes to the nanowires, where we demonstrate strong enhancement of fluorescence of these complexes due to plasmonic interactions. Additional effects associated with controlled geometry of this assembly will be discussed. Next, we describe the application of silver nanowires for enhancing absorption of organic polymers and macromolecular systems used in organic electronics. In this case, optical spectroscopy allows elucidating the processes responsible for the observed effects and enables for further optimization of actual devices. The final part of the presentation will focus on applying silver nanowires as a sensing platform for various species. Particular emphasis will be placed on methods of spatial positioning of such nanowires in a controlled manner on the surface, as this seems to be the key for any possible application.

Abstract
In this presentation, we introduce our recent accomplishments on the integration of tailor-designed polymers for diverse applications. Hybrid plasmonic nanostructures comprising Au nanoparticle arrays separated from Au substrate through a temperature-sensitive poly(N-isopropylacrylamide) linker layer were constructed, and a unique plasmonic-coupling-based surface plasmon resonance sensing properties and visible light active photocatalysis were investigated. Multimetallic Core@Shell nanoparticles consisting of Au core and metalcontaining polyaniline shells were prepared and their bifunctional electrocatalytic performance was systematically investigated. Well-defined ordered arrays of plasmonic nanostructures were fabricated on stretchable poly(dimethyl siloxane) substrates and tunable plasmon-coupling-based sensing properties were comprehensively demonstrated upon extension and contraction. We studied phosphorescence emission enhancement of a purely organic phosphor system via plasmon resonance energy transfer by precisely tuning the distance between purely organic phosphor crystals and plasmonic nanostructures using layer-by-layer assembled polyelectrolyte multilayers as a dielectric spacer. We demonstrate a viable laser interference lithography technique enabling the development of high-performance plasmonic organic photovoltaic (OPV) devices. Ag nanodot arrays with optimized configuration embedded in poly(3,4-ethylenedioxythiophene):pol y(styre-esulfonate) hole transport layer remarkably enhanced the average power conversion efficiency by ~34.4% compared to the pristine device. Hierarchically organized porous carbonized-Co3O4 inverse opal nanostructures were synthesized via complementary colloid and block copolymer self-assembly, where the triblock copolymer Pluronic P123 acts as the template and the carbon source. These highly ordered porous inverse opal nanostructures with high surface area display synergistic properties of high energy density and promising bifunctional electrocatalytic activity toward both the oxygen reduction reaction and oxygen evolution reaction in Li-air battery.

Abstract
For millions of years, nature utilizes microporous polymeric materials of well-controlled structures of skeletal walls and pores for their functions. The structures of synthetic microporous polymers are commonly limited to architectures of isolated pores, although their preparation methods have been developed for the critical roles in various applications. The directional melt crystallization of solvent, a relatively new versatile preparation method to produce aligned pores in the forms of 3D patterns, has produced porous structures of Voronoi and honeycomb-like architecture morphology. By developing adequate conditions for different polymers, we have produced various materials having ordered microchannels. The important parameters, crystallization rate and direction were controlled by temperature gradient control in 3D space using a home-made apparatus to prepare defect-free materials having well-ordered through-thickness microchannels. As crystals nucleate and grow, solutes form cryoconcentrate phases, which become skeletal portions, and crystallized solvents become pores after sublimation. The defect-free films and cylinders of through-thickness porosity could be prepared. With the support of nanotemplates, nanospheres, nanorods, and nanomembranes could be prepared too. This directional crystallization method controlling pore morphology offers a versatile route to prepare unique porous polymers and composites for future environmental, biomedical, and electronics applications.

Abstract
Native chemical ligation (NCL) is an attractive method to covalently cross-link polymers, because of its ability to react under physiological conditions avoiding the use of toxic reagents and catalysts, making this method very biofriendly. Since NCL is a very specific ligation between N-terminal cysteines and thioesters, side reactions with biomolecules can be ruled out and therefore NCL is expected to be highly compatible with encapsulated drugs. In this study, native chemical ligation (NCL) was used as a selective crosslinking method to form core-crosslinked thermosensitive polymeric micelles for drug delivery applications. To this end, two ABA triblock copolymers consisting of polyethylene glycol (PEG) as midblock and thermosensitive poly isopropylacrylamide (PNIPAM) outer blocks decorated with either cysteine (NIPAMco-HPMA-Cys)-PEG-P(NIPAM-co-HPMA-Cys) (PNC) or thioester P(NIPAM-co-HPMA-ETSA)-PEG-P(NIPAM-co-HPMAETSA) (PNE) functionalities were synthesized by atom transfer radical polymerization (ATRP). Mixing of these polymers in aqueous solution followed by heating to 50ºC resulted in the formation of thermosensitive flower-like micelles. Subsequently, native chemical ligation in the core of micelles resulted in stabilization of the micelles with an average diameter of 65 nm at 37°C. Decreasing the temperature to 10°C only affected the size of the micelles (increased to 90 nm) but hardly affected the polydispersity index (PDI) and aggregation number (Nagg), confirming covalent stabilization of the micelles by NCL. Notably, by simply adjusting the molar ratio between the polymers, the extra cysteine or thioester moieties could be used for conjugation of functional molecules. Furthermore, in vitro cell experiments demonstrated that fluorescently labeled micelles were successfully taken up by HeLa cells, while cell viability remained high even at high micelle concentrations. These results demonstrate the potential of these micelles for drug delivery applications.

Abstract
Nanostructured materials based on aromatic heterocyclic polymers, polyheteroarylenes (PHA) are now widely common in photovoltaics, membrane technologies, sensor and electrochemical devices, etc. New PHAs convertible by electrospinning to nanofiber mats are demanded on modern state of nanotechnology for example as high performance carbonaceous material of gas diffusion electrodes (GDE) for hydrogen-air polymer electrolyte membrane fuel cell (PEMFC). The spinnability of polyheteroarylenes was not a subject of large investigations. The process of PHA electrospinning is a very challenging task. There are no general methods which would allow obtaining an electrospun material certainly. Failing to find a right set of electrospinning conditions may lead to the impossibility of nanofiber formation. Hence, many parameters of the electrospinning process should be found empirically, which in some cases is a long and routine process. Only few papers describe nanofiber materials based on some polyimides, m-polybenzimidazole (m-PBI) and semi-ladder PIM-1 obtained only on so called “needle” setups. Elmarco’s first “needle-free” electrospinning equipment Nanospider™ is proved by industrial operation; a technology based on spinning from a free liquid surface. Needle-free process guarantees optimal distance between Taylor cones, excellent web and fiber uniformity, simplicity of design, robustness against clogging of a spinneret, increased productivity due to the simultaneous operation of numerous jets. The lecture will be devoted to the production of new high-tech PHAs nanofibers and non-woven materials eminently suitable for electrochemical applications.

Abstract
Organic electronics, based on semiconducting and conducting polymers, have been extensively investigated in the past two decades and have found commercial applications in lighting panels, smartphone screens, and TV screens using OLEDs (organic light emitting diodes) technology. Many other applications are foreseen to reach the commercial maturity in future in areas such as transistors, sensors and photovoltaics. Organic electronic devices, apart from consumer applications, are paving the path for key applications at the interface between electronics and biology, such as in polymer electrodes for recording and stimulating neural activity in neurological diseases. In such applications, organic polymers are very attractive candidates due to their distinct property of mixed conduction: the ability to transport both electron/holes and ionic species. Additionally, conducting polymers offer the possibility to tune their surface properties (e.g., wettability or chemical reactivity) by changing their oxidation state, thus promoting or hindering the adhesion of biomolecules. This feature can be particularly useful for enhancing the biocompatibility of implantable electrodes. My talk will deal with processing and characterization of conducting polymer films and devices for flexible, stretchable and healable electronics. This talk will particularly focus on micro-patterning of conducting polymer films for flexible and stretchable devices and on healable of conducting polymer films.

Abstract
The ability of plants to convert solar energy into chemical energy via photoredox processes (natural photosynthesis) has inspired generations of chemists to try to reproduce such systems. Lately, the use of visible light photoredox catalysis in organic chemistry has enabled the synthesis of known chemical compounds through novel synthetic routes, eliminating side reactions and complex purification procedures. Recently, we have successfully implemented photoredox catalysis in polymer chemistry leading to the development of novel light-induced polymerizations, namely PET-RAFT technology, which involves the reversible deactivation of thiocarbonylthio compounds (RAFT agents) by photoredox catalysts via a photoinduced electron or energy transfer (PET) process. In this technology, ppm amount of photoredox catalyst is employed to catalyze RAFT agent and generate radicals for subsequent polymerization, instead of external radical initiator in the traditional RAFT formulation. The RAFT agent plays the role of initiator, chain transfer agent and termination agent. Although this technology was developed from traditional RAFT polymerization with minor changes in formulation, it presented different reaction mechanisms and offered a number of significantly “green” attributes to living radical polymerizations, including: (1) low energy consumption and mild reaction conditions, (2) spatial and temporal control on radical polymerization, (3) high oxygen tolerance, (4) versatile photocatalysts and (5) selective polymerization activation. In this talk, these benefits from PETRAFT technology will be summarized and demonstrated by our recent results. This technology is not only useful in contributing to the development of green chemistry and sustainable polymer manufacturing, but also in providing opportunities for the innovation of new methods of organic and polymer synthesis.

Abstract
Micro-sized giant vesicles are a possible artificial model of biomembrane for cells and organelles, such as erythrocytes, mitochondria, and chloroplasts based on the similarities in size and structure. In recent years, a novel artificial biomembrane model has been established using giant vesicles comprised of amphiphilic poly(methacrylic acid)-block-poly(methyl methacrylate-random-methacrylic acid) diblock copolymers. The polymer giant vesicles had some similarities to biomembrane, not only in size and structure but also in the formation mechanisms, morphological transformation, membrane permeability, and stimulus-responsiveness. This paper describes the preparation and morphological transformation of new giant vesicles supporting amino groups on the hydrophilic shells through the nitroxidemediated photo-controlled/living radical polymerization (photoNMP)-induced self-assembly, with the aim of establishing an artificial model more suitable to biomembrane. The giant vesicles were prepared by the block copolymerization of a methacrylate ester supporting an amino group and methyl methacrylate using the photo-NMP technique in methanol at room temperature by irradiation with a high-pressure UV lamp. The photo-NMPinduced self-assembly produced spherical vesicles with the hydrophilic phase of the amine-containing polymethacrylate blocks and the hydrophobic core of the poly(methyl methacrylate) blocks. The size and morphology of the vesicles were dependent on the lengths of the hydrophilic and hydrophobic blocks of the copolymers. It was found that the vesicles were pH-sensitive and disrupted in an acidic solution. Their thermo-responsive behavior will be also described.

Abstract
Poly(ether-b-amide) multiblock copolymers (PEBA) are a class of important thermoplastic elastomers (TPE) s, due to the tuneable properties with variable polyether soft segments (SS)s that realizes the reliable mechanical strength. We have studied packing behaviour of a series of N-alkylated polyamides1)-2) and polyimines3), and recently developed a rapid synthetic strategy of a novel type PEBA consisting of monodisperse poly(4-N-methyl benzamide) (PMBA) with poly(propylene oxide) (PPO). The resulting block copolymer shows phase-segregated structure with two distinct glass transition temperatures (Tg)s of -65 and above 50°C. Considering the experimental results of no phase segregation of the copolymer based on polydisperse PMBA (Mw/Mn > 1.4) with PPO, the monodisperse PMBA segment should play a critical role in the phase separation behaviour. The soft segment was then replaced from amorphous PPO into crystalline poly(ethylene glycol) (PEG), resulting in considerably distinctive phase segregation behaviour, probably due to the foreclosing effect of PEG crystal phase to PMBA segment. The dual crystalline phases realize a novel shape memory polymer (SMP) as depicted in Figure 1. In our system, the temporally shape is formed at above 60oC (melting temperature (Tm) of PEG), and fixed below the temperature. Once the material is heated above the temperature, the original shape is promptly recovered. It is noticeable that the Tm of PMBA was increased from 208 to 232oC in DSC 1st and 2nd measurements while the Tm of PEG was almost same at 52°C. The annealing of the block copolymer was performed from 200 to 240°C, affording the promotion of the higher crystalline state of PEG segment. The polarized optical microscope observation indicated the growth of the PEG crystal in this annealing treatment. The finally obtained SMP film of the block copolymer shows the tensile modulus, strength, and elongation at breaks of 233 MPa, 10 MPa, and 100%, respectively. The properties of SMP were controllable with the change of two segments within the block copolymer.

Abstract
Among polymeric materials, polyolefins are clear leaders with respect to both world production scale and sustainability. Produced in solvent-free and environmentally friendly processes, they combine high resource-, eco-, energy- and cost-efficiency with low weight and outstanding versatility in terms of properties, processing, applications, and recycling. However, to compete with metals they require reinforcement by alien materials which impair recycling and processing. Special processing technologies such as lamination of stretched tapes and fiber technology are required to produce “all polyolefin composites” in which both matrix and reinforcing phases consist of polyolefin. At the beginning of the 21st century, remarkable progress in multisite polymerization catalysis enables to produce reactor blends with tailored molar mass distribution which form extended-chain polyolefin during injection molding and extrusion, typical for commodity polyolefins. Robust chromium sites produce nanophase-separated ultrahigh molar mass polyethylene (UHMWPE) unaffected by other sites during ethylene polymerization on supported multisite catalysts. The site blend ratio governs ultrabroad PE molar mass distributions and nanostructures with unprecedented precision. Owing to significantly reduced UHMWPE entanglement, reactor blends with high UHMWPE content (>20 wt.-%) are melt processable by classical injection molding. HDPE wax serves as a processing aid which cocristallizes and does not cause emission and odor problems. This in situ formation of nanophase-separated fiberlike extended chain UHMWPE, with an average diameter of 80 nm, effectively reinforces the HDPE matrix as expressed by significantly improved strength/stiffness/toughness balance. In addition to tailoring two- and three-site catalysts systems and reactor blends, nanophase-separated UHMWPE embedded in HDPE wax represents a versatile new additive enabling fabrication of allpolyethylene composites by melt compounding without affecting ethylene polymerization of commodity polyethylenes. Hence, this versatile route to sustainable all-polyethylene composites holds great promise for converting commodity polyolefin materials into high performance engineering materials without impairing melt processing, sustainability and facile recycling. Unlike common polyolefin nanocomposites, neither handling of problematic nanofillers nor special composite processing is required.

Title: Nanocontainers based on biodegradable polymer and anionic liposomes
14:05-14:30
Biography
Anna A. Efimova graduated from Faculty of Chemistry, M.V. Lomonosov Moscow State University. In 1996 defended Ph.D. thesis. Since 1996- Research Scientist, since 2008- Associate Professor at Polymer Department of Moscow State University. In 2004 awarded with the certificate of honour of the Ministry of Education. Author or co-author of more than 40 scientific publications. Research interests are associated with the interaction of polymers and interpolymer complexes with colloid and liposomal dispersions, structural rearrangements in lipid bilayers under the polymer adsorption, polymer-induced transport of small molecules through the lipid membrane, adsorption of liposomes on the surface of (bio) colloids, biodegradable and stimuli-sensitive multiliposomal containers for the immobilization of biologically active substances..
Abstract
Liposomes are widely used in medicine for encapsulation of biologically active compounds. Multi-liposome assembly composed of liposomes loaded with different fillings could enable controlled delivery of the medicines in a desirable ratio. In this work, we suggest a universal approach for preparation of biodegradable multiliposomal containers through electrostatic adsorption of liposomes on the surface of polymer nanoparticles. Firstly, we describe the preparation and properties of nanoconjugates with the “core-shell” structure in which the micellar core from a block copolymer of polylactide and polyoxyethylene is covered by a monolayer of small unilamellar liposomes. It was shown that one micelle could bind 5–6 anionic liposomes. The resulting nanoconjugate was stable in a physiological solution with [NaCl] = 0.15 M. At the same time, the nanoconjugate degraded, being attacked by proteolytic enzymes, down to 10–15 nm particles, that was accompanied by a complete release of the encapsulated antitumor antibiotic doxorubicin into surrounding solution. In the second part of the study, anionic liposomes were adsorbed on the surface of cationic chitosan nanoparticles. Chitosan is a commercially available polycationic biopolymer of natural origin that is known for being biocompatible and biodegradable. Each chitosan particle could adsorb up to 100 anionic liposomes. The conjugates demonstrated stability towards dissociation in physiological media. The complexes were biodegradable, which eventually decomposed after addition of enzymes. It was found that chitosan-liposome complex and the products of its biodegradation were non-toxic in a wide range of concentrations. Thus, the findings of this work seem to be promising in the field of drug delivery. This work was supported by the Russian Science Foundation (project no. 14-13-00255).

Abstract
Polymer composite is a hot topic for a huge number of applications. From aerospace to everyday life, composites are becoming very popular. However, two issues have to be duly considered when a large-scale application is targeted, namely the economic and the environmental impact point of view. For the first, it will be critical to decrease the composite price while improving the properties (e.g. mechanical, electrical ones). For the second, to use of recycled or bio-derived materials is sought. In particular, in the field of polymer composites with carbon fillers, a recent trend is to use biochar in substitution to the other carbon fillers (e.g. carbon nanotubes, graphene). Biochar is a charcoal used normally as a soil amendment in agriculture. However, as it is stable and rich in carbon. Because of its high carbon content, it is a good candidate as a substitute for costlier and higher environment impact carbon forms. In this work, we will present recent achievements in the field of polymer composite based on biochar and will compare results obtained used biochar with those obtained with the other carbon fillers.

Title: Synthetic biology for intracellular and secretory production of polymerized enantiopure ester-products in microbial platform
09:00-09:35
Biography
Abstract
In our previous study, the first incorporation of lactate (D-LA) into the P(3HB) backbone in the Escherichia coli-based microbial factory carrying a newly developed D-LA-polymerizing enzyme LPE was reported [1,2]. LPE was one of the artificially evolved PHA synthases through our long-term enzyme engineering studies [3,4]. In the second generation, LPE has led us to further expand the range of structural diversity of PHA members other than LA-based polymers. New unnatural monomeric constituents such as glycolic acid and 2-hydroxybutyrate can also be polymerized by LPE. Like these, the study intends to synthesize the chiral copolymers with various monomer compositions, owing to the extremely high enantio-selectivity and broad substrate specificity of LPE catalyst [5]. In this conference, the main focus will be on the overview of biosynthesis and properties of LPE-catalyzed polymers. The possibility of “secretion” of polymerized ester-products by microbial platform should be a promising issue to overcome the cell volume limitation in the large amount of production of microbial polymers. Fortunately, we have met the “secretion” of low-molecular-weight D-LA-based polymers [or D-LA-based oligomers (D-LAOs)] [6)] The second topic will be about the first observation of microbial secretion of D-LAOs and its advanced microbial secretion platform through the chain transfer reaction and modified cultivation conditions. Furthermore, synthesis of lactate (LA)-based poly(ester-urethane) using hydroxyl-terminated LA-based oligomers from a microbial secretion system will be presented.

His research interests range from photochemistry, including photoinitiators and molecular switches, to the design of new nanostructured composites and conductive inks for printed electronics.
Abstract
Photoinitiators, which can be readily immobilized on surfaces via silanization, have gained considerable attention of both scientists and engineers. One of the reasons for this interest is that immobilized initiators lead to a covalent linkage between the surface and the resulting polymer chain. Thus, immobilized photoinitiators are expected not to migrate out of the polymer network, which reduces potential health risks. The synthesis of a range of short- and long-wavelength absorbing photoinitiators bearing alkoxysilyl groups will be presented. In all cases, the synthesis starts from commercially available products, Irgacure 2959 or Irgacure TPO-L, and takes 1–4 steps. Both free and immobilized initiators are characterized and tested with regard to their efficiency in acrylic and thiol-ene systems. The findings confirm the good applicability of the nanoparticle-immobilized photoinitiators in the preparation of nanocomposite materials.

Title: Novel polymer latexes by photoactivated ring-opening metathesis polymerization in miniemulsion via the in situ generation of ruthenium-arene catalyst through photolatent N-heterocyclic carbene ligand
12:05-12:30
Biography
Loic Pichavant is a Post-doctoral Researcher at the Laboratoire de Chimie des Polymeres Organiques (LCPO) at the University of Bordeaux (France) since 2010. His research interests deal with the formation of nano-objects by ring-opening metathesis polymerization in dispersed media (dispersion; miniemulsion) of cyclo-olefins and their use in biomedical applications (nano-carriers; drug delivery systems). He obtained a PhD Degree in 2009 from the University of Reims Champagnes-Ardennes, working on the synthesis of new biosourced monomers and their polymerization by photoinitiated free radical polymerization.
Abstract
Many useful polymers as polynorbornene (PNb) or polydicyclopentadiene (PDCPD), having interesting applications as optical components, high impact thermosets or shock absorbers, are prepared by ring-opening metathesis polymerization (ROMP). However, the air sensitivity and the lack of processability of the metalbased catalysts used for ROMP is a drag for their implementation at industrial scale. Nevertheless, in situ generation/activation of ROMP catalysts employing stimuli like temperature, pH or UV irradiation can palliate this drawback. Among them, photoactivable ROMP catalysts are certainly the most interesting and have often relied on a ligand dissociation/rearrangement under UV light. In this project, we propose an alternative pathway to generate active ruthenium complexes under UV light. The latter employs photosensitive imidazolium salts to generate N-heterocyclic carbene (NHC) under irradiation that can be subsequently employed as ligands. As such, when associated with the inactive [RuCl2(p-cymene)]2 dimer, the system allows the formation of the Noels’ catalyst RuCl2(pcymene)(NHC) in situ under UV light. Polymer latexes, commonly synthesized by emulsion polymerization, have high industrial interest. However, few contributions have been reported regarding polymer latexes obtained by ROMP, first due to the high sensitivity of the active species involved and also because of difficulties to mix ROMP initiators and monomers without causing a premature polymerization. The use of photolatent catalytic systems permit to let go off these drawbacks and can afford a new range of polymer latex by ROMP which cannot be prepared by other routes. In this contribution, the synthesis of PNb by ROMP with two photolatent catalytic systems will be first presented. Then this strategy will be transferred in miniemulsion conditions to prove the ability of this system to form PNb latexes.

His area of interest is situated at the junction of colloïdal and polymer sciences with a specification for Pickering emulsions based on cellulose nanocrystals.
Abstract
Pickering emulsions are based on amphiphilic particle stabilizers, which adsorb irreversibly at the liquid-liquid interface and form a rigid structure around the droplets. Amongst these particles, cellulose nanocrystals (CNCs) have demonstrated good performances as Pickering stabilizers for oil in water (o/w) emulsions in the presence of salt additives, or after chemical functionalization of the surface. In this work, a wide range of o/w emulsions of monomers were stabilized by amphiphilic modified CNCs. These Pickering emulsions subsequently serve as vessel to perform radical polymerization. In the first system, the CNCs are modified with a non-reactive moiety to tailor the hydrophobic/hydrophilic balance and the polymerization in the droplet is initiated by thermal radical initiator solubilized in the monomer. In the second system, the CNCs are modified with an ATRP initiator, in order to start the polymerization directly from the shell of the droplets to the center of the beads, in a controlled way. In this presentation, we will characterize both the emulsions and the corresponding latexes in a colloidal and polymeric point of view.
