Testo completoEnergy developments have brought hexagonal boron nitride-based materials increasing interest for future materials and technologies. The objective of this thesis concerns the preparation of BN shapes for energy applications including fiber-reinforced BN composites, BN-based nanocomposites and BN foams. Fiber-reinforced BN composite and BN nanocomposites display potential as tiles for protection limiters for the Ion Cyclotron Range Frequency antennas in fusion nuclear reactors. Porous BN materials have interests as host material for hydrogen storage and as catalyst supports. The Polymer-Derived Ceramics route which offers new preparation opportunities in chemistry and ceramic sciences is applied to manufacture shaped BN-based materials.Firstly, in the context of C/BN composite, polyborazylene vacuum-assisted infiltration and pyrolysis process was successfully introduced. We focused on the design, elaboration and properties of the C/BN composite through the study of the (1) synthesis and polymerization of borazine, (2) the polyborazylene-to-boron nitride conversion, (3) the morphological texture and mechanical properties of derived C/BN composites. We firstly demonstrated that it is possible to obtain dense-derived C/BN composites (density: 1.773 g cm-3, open porosity: 5.09%) by tuning the viscosity of polyborazylene in the infiltration process. SEM observation presented a very strong bonding between fibers and matrix. TGA under air analysis confirmed the improved oxidation resistance property of C/BN composite compared with C fiber.Secondly, we investigated the design, processing, and properties of transition metal-containing boron nitride nanocomposites from polymetalloborazine. With proper choice of boron nitride precursor, and by controlling the B/M ratio (M = Ti, Zr, Hf), a set of representative polymetalloborazines has been prepared as precursors of nanocomposites. In the reaction of BN source with metal precursor leading to polymetalloborazines, two main mechanisms are mainly concerned: N-H and B-H units of BN percursor react with N-alkyl groups presented in metal precursors. After its pyrolysis under ammonia up to 1000 oC then nitrogen from 1000 to 1500oC, the derived nanocomposites reveal the presence of metal nitride nanocrystales with an average diameter of 6.5 nm homogeneously embedded in a poorly crystallized boron nitride matrix. A preliminary study is presented on the preparation of monolith-type nanocomposites from selected polytitanoborazines. Finally, we applied two PDCs route-based strategies to prepare hierarchically porous and micro cellular BN foams. In the first strategy, monolith-type BN foams with a hierarchical porosity were synthesized from polyborazylene using an integrative chemistry combined-based sequence set-up that consists of the impregnation of silica and carbonaceous templates followed by pyrolysis process and elimination of the template. These novel porous BN architectures display hierarchical and high porosity (76 %) with an open-cell interconnected macroporosity and a surface area up to 300 m2g-1. In the second strategy, a sacrificial processing route has been proposed to fabricate micro cellular BN foams with a porosity of 79 % from a mixture of polyborazylene and poly(methylmethacrylate) (PMMA) microbeads by warm-pressing followed by pyrolysis consisting of the burn-out of PMMA while polyborazylene is converted into BN. These novel BN foams display potential as catalyst supports and host material for hydrogen storage

Testo completoThis work deals with hydric and thermal characterization of cob, hemp and lime coating, hemp mortar and hemp wool. The first part deals with environmental quality of building materials and presents the ones studied. Their structural physical characteristics are given. The wet fixing and transfer are then studied by sorption and permeability measurement. The results obtained are compared with the porous structure and are coupled in order to calculate the isothermal hydric diffusivity coefficient. Lastly, the thermal characteristics of the materials are measured for three wet contents. The results are compared with those obtained for other materials. Simulations enable to compare the heating needs of a building with walls made of different materials (insulated concrete blocks, cob, hemp mortar). The results show that the heating needs for the studied materials are similar for lower environmental impacts all the building life cycle long

Testo completoVarious photo-induced energy and energy transfer processes were investigated in solution and in the film by transient absorption and fluorescence spectroscopies for two types of solar cells. Combined with other experiments and through a global analysis, those ultrafast phenomena with their lifetimes were observed and the photo-induced scenarios were determined. The insight understanding of molecular materials could help chemists to design efficient solar cells.The first study about the influence of chemical designs on charge formation and separation involves different donor moieties and different solvents and the results were explained by Marcus-Jortner theory combined with quantum calculationThe second investigation is about Fe(II) complexes as photosensitizers for dye-sensitized solar cells. A series of homo- and heteroleptic Fe(II) complexes with carbene and terpyridine ligands have been studied in solution and in the film. The record triplet metal-to-ligand charge transfer state lifetime of Fe(II) complex is achieved in solution. The further understanding in the film is in progress

Testo completoThis thesis is specifically aimed at studying the feasibility and the performance of a hybrid device VN/KOHaq/Co3O4 so as to enhance the volumetric energy and power density of electrochemical capacitor (ECs). The two electrode materials present a density 8 times larger than the usual capacitive carbon material, used in ECs, as well as a larger capacity per mass unit due to their pseudocapacitive (VN) and faradaic (C0304) properties. Considering that high power density and long cycle life make ECs attractive for some applications, it is important to ensure that each material fulfills these specifications. As a first step, the feasibility of establishing a molecular bridge between Co3O4 nanoparticles and carbon fibers and its effect on the electrochemical performance of the nanocomposite material were investigated. In a second phase, this films of vanadium nitride were prepared in order to determine the suitable conditions required to ensure a long cycle life of the electrode. Moreover, the charge storage processes of these VN electrodes were investigated in different electrolytes. Finally, a VN/KOHaq lCo3O4 microdevice was realized and electrochemically characterized

Testo completoWe have studied the conductivity of the composite material made of micron-sized nickel particles embedded in a silicone elastomer matrix in response to the applied pressure, temperature and magnetic field. The composite was cured at 80°C or at the ambient temperature and in the presence of an external magnetic field, in such a way that the magnetic particles formed structures aligned with the field. The samples cured at room temperature appeared to be non-conductive at zero pressure but very sensitive to the applied pressure. The resistance of these samples can vary from a few G at zero pressure to a few for a pressure ranging between 20 and 200 kPa, depending on the nature of conductive particles. For the same type of the composite, we have also obtained a very strong magnetoresistance - more than four orders of magnitude variation in resistance for a field ranging between 0 and 200 kA/m. However, the samples structured at 80°C show a low initial resistance at the end of cooling, and are much less sensitive to the applied pressure. We used these samples to study the thermoresistance: while heating, the resistance increases from a few to a few G We have developed a model to predict the behavior of these piezoresistive materials, which takes into account the surface roughness and the thickness of the oxide layer. Using this model, we characterized the residual thickness of the polymer layer between particles as well as the behaviour of such surface layer in the presence of a mechanical stress

Testo completoOur approach to alleviate the solar intermittency is to combine, in a single photo-electrochemical cell, solar energy conversion and storage. Starting from a Li-ion battery configuration, we propose to use Li-ion host photo-electrodes, which could both harvest solar energy and store it. We will be presenting the case of mesoporous TiO2 anatase, as a positive electrode. The illumination of the lithiated electrode (after discharge) induces a lithium-ion extraction reaction (i.e. the recharge of the battery), opening the way to Li-ion photo-rechargeable batteries. Photo-extraction of lithium ions at open circuit voltage and during electrochemical cycling was demonstrated. The holes’ photo-generated seems to oxidize the Ti3+ into Ti4+ resulting in the extraction of the lithium ion, however the fate of the photo-electrons was not elucidated. In this thesis, we chose to control and orient the fate of the electrons by adding water as a photo-electron acceptor, thereby choosing a water-based electrolyte (i.e. water-in-salt, WIS) to also be able to access a large storage capacity of lithium ions and produce a storage molecule, the dihydrogen. Depending of the state of charge of the battery, the electrode composition varies a lot: from a single crystalline phase to a two-phase material. The impact of this composition change in the dynamics of, the production of hydrogen and the light-induced processes, both will be discussed in this thesis. This work constitutes a proof of concept that low potential Li-ion batteries could solely be recharged by exposure to light
