Full textThe aim of this PhD work is to replace current gloves of gloveboxes used in nuclear area by elastomer discs which could take the shape of the arm of an operator and come back to their original shape when the arm is removed. The goal of the work is to design and study a material meeting the following specifications: at least 2 000 % strain at break, very high elastic properties, tear and radiation resistant. A bibliographic study showed that the most relevant materials are thermoplastic elastomers. As a consequence, two kinds of these materials were formulated. First ones are thermoplastic polyurethane elastomers. The influence of stoichiometric ratios and different chain extenders on mechanical properties was studied. These materials are too viscous to match the specifications but an interesting linear relation between flow stress and viscosity ratio was observed. Second ones are Styrene-Ethylene-Butylene-Styrene copolymers (SEBS). Studies on the influence of the process and incorporation of plasticizers, nanoparticules or polyurethane were carried out. It was highlighted that the process strongly influences mechanical properties and addition of nanoparticules or polyurethane can increase some of these properties. On the whole, the materials developed are very close to these of hyperelastic materials

Full textThis work deals with the design of molecular multifunctional photoswitchable systems incorporating dimethyldihydropyrene (DHP) photochromic unit and with their implantation and characterization in switchable devices.We show that a tetra pyridinium-appended DHP derivative displays interesting photoswitchable optical properties, emission and excitation fluorescence and electronic communication. Combining DHP pyridine-substituted ligand with porphyrin complex via axial coordination enhances the photoinduced DHP ring-opening reaction. Additionally, associating photoresponsive DHP unit with electron-responsive transition metal complexes confers additional redox properties to the resulting hybrid system. The DHP core photo-isomerization proceeds much more efficiently when the metal complexes and the DHP moiety are connected through pyridinium-bridge vs phenyl bridge. The resulting systems are used for the conception of new multi-addressable photo- and redox- switches. These assemblies are applied for the design of photoswitchable coordination polymers developed in solution or immobilized onto ITO. Photochromic films based on Zn2+ exhibit conductance properties that can be tuned optically and thermally according to the photostate of the photochromic unit. The DHP core associated with a pyrene entity and immobilized onto carbon nanotube electrode via -stacking acts as a switchable material. Finally, we report the possibility of controlling 1O2 production by light irradiation or by heating, of an ITO surface functionalized by pyridinium-substituted DHP derivatives. In the presence of dioxygen, this DHP derivative plays the role of an O2 sensitizer. The photogenerated 1O2 reacts with the open-ring isomer to afford the corresponding endoperoxyde species which then releases 1O2 thermally

Full textThis work deals with the synthesis and characterizations of NaSICON-type ionic conducting ceramics of general formula Na1^xM2->Six. 4,P:. X__. 0:: \vith 1. 8 < x < 2. 2 and 0 < y < x/4. New compositions have been synthesized Tvv:;h complete substitution of zirconium by hathium. Syntheses were made using the sci-gei method; the synthesized precursors have been characterized by coupled TDA-TGA technique. The oxides obtained after precursors pyrolysis were identified using XRD technique. A study of sintering was carried out using dilatometry in order to select the most adapted thermal cycle to these ceramics. After sintering the oxides, the obtained ceramics have been characterized from their electric conductivity point of view. The complex impedance spectroscopy enabled us to differentiate the conductivity related to the grains from the conductivity related to grain boundaries and to reveal the influence of porosity towards total conductivity. The results highlight that these new ceramics conductivity is remarkable, compare to the values of total conductivity at 300K (about 10~4 S. Cm"!) published in the literature for other NaSICON-type materials

Full textThe scientific problem of this work focuses on the role of alumina parameters on physico-chemical changes of materials of the CaO-Al2O3 system. The objective of this study was to identify the parameters of alumina affecting the physico-chemical interactions within the system CaO-Al2O3 in order to optimize the mechanical behaviour of conventional refractory concrete in the temperature range 800-1200°C. The conventional refractory concretes are composed of heterogeneous aggregates of tabular alumina and a cement matrix, this one consisting of clinker and fine alumina. The temperature zone between dehydration and ceramization is not studied so much in the literature. The methodology adopted, because of the complexity of this kind of materials, has been modelling materials "models" to control the microstructure and to take into account the influence of one parameter at a time and establish relationships between the parameters of development, microstructure and mechanical properties.The first part of this work has studied the intrinsic properties of the binding phase, and has highlighted parameters of alumina (specific surface area, morphology, and impurities) having an influence on the microstructural parameters improving reactivity and mechanical strength of the cement matrix. The CA2 content and the degree of homogeneity of the system are the two main parameters that improve the reactivity of system. A good reactivity of the cement matrix improves this mechanical strength by the effects of microstructure caused by the reactive sintering. It has been shown that these kinds of microstructural parameters are obtained for alumina with high surface area and alumina containing soda or silica. A statistical model has been developed in order to predict the mechanical behaviour of cementitious matrices with the selected alumina. These studies, confronted with results from the literature, confirmed that the calcium aluminates are formed by diffusion of Ca2+ to the alumina through the calcium aluminates rich in lime. The second part of this study highlights the interactions between cement matrix and aggregates of tabular alumina, and put forward the formation of interphases between the two constituents. These interphases are especially significant and cohesive for cementitious matrices composed of alumina rich in silica and soda with a high specific surface area, for lime-enriched matrices (with the same A/C), and for matrices with controlled dimensional variations. In this study, we have identified drivers to optimize the material properties of the system CaO-Al2O3 in the intermediate temperature range 800-1200 °C

Full textIn the field of aeronautical braking, steel is gradually replaced by carbon/carbon (C/C) composite. These materials are very sensitive to the conditions of braking and exhibit high or low friction and wear regimes. This study agree on the existence of these different regimes during simulations of a whole takeoff/landing operation. We determined coefficients of friction and wear rates relating to each of these regime and the evolutions of rubbing surface and wear debris which are associated to each of them. Simulated experiments of identical brakings highlighted the correlation between these regimes and phenomena of surface polishing and specific mechanisms of agglomeration, compaction and ejection from the contact of third body. We propose a dynamic model of wear mechanisms during takeoff/landing operations. However a purely mechanical approach of the C/C composites tribology is not sufficient. The physicochemical study of the debris showed the difference of quantity, nature and relative proportion of the various oxygenated species in the debris. This study highlighted the contribution of specific oxygen groups to the tribological response of the C/C discs
