Texto completo da fonteThe aim of this thesis is to develop efficient semi-conducting organic materials for organic photovoltaics. This work is focuses on the optimization of electron-donor organic semiconductors for the preparation of bulk heterojunction devices, in blend with a fullerene derivative used as electron-acceptor material. More specifically, it is to perform a systematic optimization study of two reference families (macromolecular and molecular respectively) from the laboratory, which have already led to interesting photovoltaic performances. For this, we followed a structured and systematic approach targeting the most relevant chemical parameters to be varied. To determine the properties of new materials synthesized, spectroscopic, electrochemical, structural, charge transport and photovoltaic characterizations were systematically made

Texto completo da fonteThis thesis is part of the ANR project “PROCOM” from the Mat&Pro program whose coordinator is EADS IW. The aim of the project is the development of a process likely to be scaled up industrially to produce fibrous reinforcements for high performance composites. The project incorporates new concepts in nano / micro-scale and an electrochemical surface treatment. This PhD work presents the synthesis of an electronically conductive polymer (polypyrrole) by an electrochemical route, on the surface of hybrid reinforcements which are carbon fibers grafted by carbon nanotubes (CNTs). At first, the polymer synthesis has been optimized and the influence of different electrochemical parameters on the doping level and the thickness of the polymer layer was investigated. The parameters studied were the applied potential, the polymerization time, the nature of the electrolyte and the dopant. Then, the influence of polymer deposition on three very important parameters was considered. These parameters are the electrical conductivity, the mechanical properties and the adhesion of CNTs on the surface of the carbon fibers. The electrical properties are important because these composites are intended to be used for the fuselage of aircraft that must be able to dissipate the current from lightning. Good intrinsic electrical properties of CNTs and the use of a conductive polymer have improved the conductive properties of reinforcements. The polymer, which is at the interface between the reinforcing hybrid fibers and the matrix, is expected to improve the mechanical properties of the final material. However, to improve this interface different pre-treatments were carried out, such as heat treatment, plasma surface functionalization and incorporation of a grafting layer. Finally, the polymer plays a protective role in the dissemination of CNTs in the atmosphere in order to avoid any health risk. In a second step, a system for the electropolymerization of hybrid fibers in continuous was implemented with the aim of developing an industrially scalable process

Texto completo da fonteCombining multiple properties into one material turns molecular materials very attractive. Moreover, bistability is often a necessary condition to manage electronic or memory devices. We present here two examples of bistabiliy. The first one consists in a thermo-activated charge re-organization on bis(ethylenedithio)tetrathiafulvalene (ET) molecules in a multifunctional material which associates an organic sub-lattice containing conductive moieties (ET molecules) and an inorganic sub-lattice containing spin (on the FeIII ion in the hexacyano-ferrate complex). Aim at describing the bistability of this system, after synthesis by electrocrystallization, crystallographic structure has been solved at different temperatures. Physical measurements under thermal variation were carried out to complete the description of the phenomena we evidenced. The second example is the spin change in FeII based complexes. First step was to elaborate an optical montage allowing under irradiation measurements suitable for various experiences. Magnetic susceptibility measurements were performed. Thermally and optically induced spin change (called LIESST effect for Light Induced Exited Spin State Trapping) were evidence
