Full textThe knowledge of the physico-chemical properties of polymer solutions for enhanced oil recovery (EOR) is crucial to optimize the process. The purpose of this work was to consolidate and complete an universal viscosity model depending on C[η] parameter. The later allows taking into account the degree of interpenetration of polymer chains (critical concentration, C*, diluted and semi-diluted solutions). Various polymer parameters have been studied as the effects of microstructures, polymer size (molar mass and dispersity) as well as chemical composition. A library of polymer models was elaborated by controlled radical polymerization (RADT/MADIX). Series of polyacrylamides, statistical and asymmetric copolymers of acrylamide-sodium acrylate and post-hydrolyzed polyacrylamides were synthesized and characterized by steric exclusion chromatography and capillary rheology and the analytical protocols and techniques were optimized. The effects of the microstructure onto dimensional, rheological and complexation physico-chemical properties were determined

Full textThis work is concerned with the study of carbon nanotubes (CNT) dispersions in a polymer matrix in order to obtain nanocomposite with unique properties. In the first part, we investigated the CNT wrapping by amphiphilic block copolymers to facilitate their suspension in aqueous solution. Based on the results, we could assess the effect on CNT dispersion quality of the molar mass of copolymers, the nature of the hydrophobic block and the length of hydrophilic block. In the second part, the incorporation of CNTs in polymer matrix was developed. Water or melt processing were chosen to control the distribution of CNTs in various polymer matrices (Polyethylene oxide, polyethylene and polymethyl methacrylate) through a prior wrapping of CNT. The studies of physical properties, including rheological and electrical properties, of nanocomposites were undertaken. Relationships between the state of dispersion, the nature of the coating and the method of preparation of composites were established

Full textThis dissertation focuses on the development of new approaches for elaboration of hybrid materials based on oligothiophenes. The first part of this work reports a one-pot method for preparing cds nanoparticles (nps) bound to oligothiophenes. Tem and x-ray diffraction show that the cds-oligothiophenes are monodisperse. The amount of oligothiophene and the nature of surface binding have been studied in detail using xps, ir, uv-visible and fluorescence spectroscopy. The major advantage of this method is that we use functionalized π-conjugated electroactive systems as ligands to control np growth. The electroactive ligand binds to the np surface and allows intimate contact between the np and the conjugated backbone, leading to better electronic communication between the two components. In the second part of this manuscript we describe the development of a new method for elaborating rod-coil polymers. The raft polymerization of mma and styrene with three different chain transfer agents, generated from oligothiophene dicarboxylate, yields polymers with narrow molecular weight distributions. Uv-visible, nmr and maldi-tof were used to confirm the presence of the expected raft agent end-groups. Attempts were made to initiate controlled radical polymerization from the surface of a cds nanoparticle modified with oligothiophenes. The last chapter reports the crystal structures of a series of mof containing oligothiophene dicarboxylate linkers. The influence of the angle of the rigid oligothiophene core is exemplified in the crystal structure of (mop-28) obtained by linking the square planar cu₂(coo)₄ paddle-wheel units with the flexible 2,2':5',2"-terthiophene-5,5"-dicarboxylate

Full textThis work deals with the study in aqueous solutions of mixtures of hydrophobically end-capped linear polyethylene oxide (PEO) on one (monofunctional) or two (difunctional) ends. Spherical micellar structures are formed by these mixtures with agregation degrees which do not depend on the fraction of difunctional PEO. Difunctional PEO allows reversible bridging between the micelles. The system is a good model for understanding the reversible agregation by varying inter-micellar attractivity. The phase diagram and the micellar association can be described and modelized by considering micelles as sticky hard spheres with attractive strength depending on the fraction of disfunctional PEO and temperature. At high concentration, a so-called hard gel of close packed micelles is formed. Static and dynamic light scattering, fluorescence and rheology have been used to investigate these systems. Anionic polymerisation has been used to synthetize hydrophobically end-capped star PEO in order to understand the influence of the architecture on the dynamics and the phase diagram of such associative systems. Hydrophilic-lipophilic balance has been changed by varying the alkyl length in order to study its influence on the associative behaviour

Full textBioelectronics is an emerging field that is aiming to combine the worlds of biology and electronics. Among all the other materials, organics present a unique set of features that renders them ideal candidates for this new field. Their soft nature gives better mechanical stability, while the fact that they can conduct both electrically and ionically makes them ideal candidates to bridge the gap between electronic devices and living tissue. In addition they provide oxide free interfaces that could interact more efficiently with biology and allow chemically modification that increase biological functionality. These ideas, together with the organic devices fabrication approaches are presented in Chapter 1.Electrodes are the main experimental tool for electrophysiology and this is why Chapter 2 presents the main physics principle behind them. Chapters 3 and 4 implement the knowledge obtained from the electrode modeling to real biological measurements. Chapter 3 presents activity recordings from Hippocampal cell cultures and Chapter 4 form pancreatic cells. Chapter 5 introduces us to a different device as it presents the Organic electrochemical transistor (OECT) and presents a read out circuit board that could facilitate OECT electrophysiological recordings. Chapter 6 closes this thesis with an application of OECT on astrocyte recordings

Full textThe additivation of diesel fuels allows operating engines at low temperatures without filter blocking and thus fulfilling legal requirements. Ethylene based copolymers such as ethylene-vinyl acetate copolymers, made by free radical polymerization at high pressure (above 2000 bars) and high temperature (above 200 °C) are frequently used as middle distillate cold flow improvers (MDFI). A new free radical copolymerization process of ethylene and vinyl acetate in organic solvent media has been developed. This process gives access to polymers close to commercial MDFI additives under tremendous less drastic conditions (under 250 bars of ethylene and 70 °C). Thanks to this process, a wide diversity (variation of the nature of the polar unit, of polymer architecture…) of ethylene based polymers was obtained. Moreover, EVA model copolymers have been synthesized by metathesis. Thanks to these numerous and diverse ethylene based polymers combined with thermal analysis and X-ray scattering studies a better understanding of the operating mode of these additives in a diesel fuel has been achieved. The structural characteristics of the polymers enabling their effectiveness as diesel fuel cold flow improvers have also been established

Full textIn the last decades, membrane separation has played an important role in many industrial processes thanks to its versatility, low energy consumption, high performances of membranes, as well as a possibility of combining membrane technologies with other separation processes. Membrane technologies gave a great contribution to the improvement of separation processes in the industrial scale thanks to a number of advantages, such as the high selectivity of the separation, the opportunity to work with thermolabile compounds, and low energy demand. Pervaporation process is an important membrane separation technique used to separate binary or multicomponent liquid mixtures including close boiling solvents, azeotrope mixtures, and isomers. During pervaporation, feed components are in the direct contact with one side of the lyophilic membrane, while the selected components are preferentially transported across the membrane to the permeate side. Membranes used in pervaporation must be characterized by high selectivity, chemical stability, and mechanical strength at high temperatures. Selectivity and transport properties of the membrane determine the overall efficiency of the separation process. The comprehensive characterization of membranes is the crucial approach and can lead to broaden the knowledge about the influence of the membrane structure and membrane preparation conditions on the equilibrium, separation, and transport characteristics of the studied membranes, in order to develop new polymer materials with the expected efficiency of the separation process. Research has been also focused on the development of the membranes filled with ILs in order to tailor the separation properties of the developed membranes used in liquid separation by pervaporation, gas separation, and separation of metal ions as well as the conducting barriers in fuel cells. ILs are characterized by good thermal stability, high ionic conductivity, negligible vapor pressure, and low melting point. Due to their numerous unique properties, polymer membranes containing ILs (polymer-ILs) possess wide range of advantages, like better separation properties than the classical polymer membranes. This fact is related with much higher molecular diffusion in ionic liquid than in polymers. Therefore, the use of polymer-ILs in separation processes would result in superior separation behavior and higher fluxes. Morphology and physicochemical properties of ILs can be “tailored” depending on the separated system in order to obtain a suitable polymer material for a given separation process without preparation of a chemically new membrane. Even though there is a growing interest in the application of polymer membranes filled with ILs, the polymer-ILs based separation processes are limited due to the losses of the unbound ionic liquid in the course of the exploitation. The PhD is realized in the frame of "co-tutelle" system between the Faculty of Chemistry at the Nicolaus Copernicus University (NCU) in Toruń, Poland (Membranes and Membrane Separation Processes Research Group) and the University of Rouen Normandy, France (Barrier Polymer Materials and Membranes (MPBM) Research Group of the Laboratory of Polymers, Biopolymers, Surfaces (PBS)). The main aim of the present PhD thesis is to elaborate novel dense membranes based on poly(vinyl alcohol) (PVA) and cellulose acetate propionate (CAP) filled with various reactive and polymerizable ILs in order to obtain the polymer-ionic liquid system in which ionic liquids are linked inside the polymer structure. The investigation of physicochemical characteristics and study of the equilibrium, barrier, and transport properties of the obtained membranes was carried out. Furthermore, the selected membranes were tested in pervaporation process in contact with water-propan-2-ol mixture, water and gas permeation measurements
