Texte intégralThis work reports the rheo-optical study of dispersion mechanisms of reinforcing fillers in an elastomer matrix under shear. The purpose of this work was to determine key parameters for dispersion in order to improve the filler dispersion step in a rubber for pneumatic application. This study showed that the dispersibility of a filler such as carbon black or silica is characterized by a critical stress to overcome and a dispersion mechanism. The dispersion study of precipitated silica grades in the shape of micropearls and of carbon black showed that the dispersion criteria for the two filler depend on the internal organization of the granules. Carbon black dispersion is dominated by the fractal organization of its aggregates. Silica micropearls present a skin-core-internal organization. The dispersion criterion for silica is linked to the skin cohesion strength. The dispersion mechanism is related to the stress propagation pathway within the micropearl and thus to the cohesion of the core. The chemical-physical treatment of silica surface during their processing enables to modify the cohesion of silica micropearls and consequently the dispersion mechanism and stress level for dispersion

Texte intégralThis thesis focuses on the incorporation of mineral fillers of erbium oxide, Er2O3, and praseodymium oxide, Pr6O11, in an elastomeric polymer matrix, in the context of an industrial project to replace the lead in radiation protection equipment. The actual purpose of this thesis was to improve the dispersion of the fillers in the matrix through chemical treatment processes of these particles. Various types of surface functionalization were used to compatibilize them with an organic matrix, in particular by grafting compounds such as phosphonic acids. Hence, several phosphonic acids have been successfully used for the functionalization of both types of fillers. The characterization of these functionalizations is an important part of this project. Innovative analysis techniques, both direct and indirect have been used for this purpose, namely Py-GC/MS to detect the chemical compounds anchored to the surface of the fillers, X-ray fluorescence and FTIR spectroscopy with a quantification target, but also a study of sedimentation kinetics of the fillers in an organic medium. Finally, composites were obtained by mixing the fillers, untreated and treated, with a polyurethane matrix. Tensile tests have clearly shown an improvement of mechanical properties for some of the composites, due to the functionalization of the fillers by phosphonic acids

Texte intégralThe objective of this study is the analysis of the dispersion of mineral fillers within a polymer matrix. This work aims is to increase the fire resistance of a polyolefin by dispersing magnesium hydroxide mineral filler. High amounts of magnesium hydroxide are needed to reach a significant performance of the fire resistance. The high loads induce a degradation of the mechanical properties of the material. In order to obtain a good dispersion and to improve the mechanical properties, a high viscosity matrix may be used. However, this causes problems during the manufacturing of the composite by extrusion because high pressures induced by a highly filled viscous matrix might block the machine. To solve this issue a less viscous matrix can be used to facilitate the processing by extrusion. Two matrices having the same physico-chemical properties but very different viscosities have been used to disperse the filler. The first part of the study concerns the identification and analysis of the elementary mechanism of dispersion, i.e. how an individual agglomerate is dispersed. Then, extrapolation to highly filled systems is carried out. The global mechanism of dispersion has been conducted in an internal mixer and characterization techniques such as scanning electronic microscopy with X-ray detection, tensile test, fractal dimension and dynamic rheometry in the melt have been used. A rheological model relating dynamic rheological measurements and the state of dispersion has been developed. The last part of the study is concerned with the optimization of the fabrication process and the dispersion of filers by twin screw extruder

Texte intégralShort-range atmospheric dispersion of ammonia emitted by agricultural sources and its subsequent deposition to soil and vegetation can lead to the degradation of sensitive ecosystems as well as soil acidification. Atmospheric concentrations and dry depositions rates of NH3 are generally higher near the emission source and environmental impacts on sensitive ecosystems are often largest at these locations. To better evaluate the impacts and their extent at the agricultural landscapes scale, scientific reviews of NH3 assessment methods recommended a comparison between different types of models at different spatial scales. In this context, we compared NH3 fluxes simulated by two atmospheric dispersion, transport and deposition models (CHIMERE and OPS-ST) for different theoretical and semi-real scenarios and for different grid cell sizes. The simulation results show that the averaged NH3 dry deposition over the investigated domains is comparable for grid cell sizes for which the models were designed. This implies that eulerian models with a km scale horizontal resolution can be used for studying the larger scale impact of NH3 on atmospheric composition despite an inadequate treatment of near source dry deposition, for which the models diverge. Meteorological conditions and grid cell size are the factors having the strongest effects on the results of the two models. NH3 dry deposition predictions can be used to map critical load exceedances, our results show that the detection of these exceedances near to the sources is better represented with OPS-ST than with CHIMERE, the latter showing an overestimation of the surfaces exceeding critical loads

Texte intégralThe aim of the present thesis is to improve the barrier properties of polycarbonate (PC), a stiff and transparent polymer used in automotive industry as material for car headlights. PC represents a place of transfer of gas molecules and vapors coming from inside and/or outside the optics and also of migration of small species (monomers, additives) within the material itself. These phenomena often lead to a loss of the PC transparency, especially with the LED technology which does not allow the condensation dissipation. In order to overcome this limitation, three different approaches allowing the increase of materials transfer resistance were chosen. The first approach consists in the cold plasma surface treatment in order to obtain a barrier organosilicon layer on the PC substrate. This layer is obtained using a mixture of oxygen with an organosilicon precursor : hexamethyldisiloxane (HMDSO), 2,4,6,8-tetramethylcyclotetrasiloxane (TMCTS) or triethoxyfluorosilane (TEOFS). The other approaches focused on the incorporation of fillers and polymer blends permit the elaboration of micro/nano-composites of PC/mica, PC/poly(m-xylene adipamide) (MXD6) polymer blends and charged PC/MXD6/mica blends. These films were prepared using a double-screw extruder equipped with mix elements allowing the improvement of the quality and dispersion of the blend. The physico-chemical characterization of the obtained materials highlights the structure/morphology/properties relationship. The plasma deposition allows an increase of the PC thermal resistance as well as its barrier properties toward water and especially gas (N₂, O₂ and CO₂). The efficiency of the plasma treatment toward water molecules strongly depends on the layer hydrophilicity and density. PC/mica composites elaborated with mix elements are found to be more barrier toward water than toward gas, while PC/MXD6 blends are more efficient toward gas than water. Thus, the addition of low mica contents in the PC/MXD6 blend allowed to further increase the water resistance of the blend by trapping effect, while maintaining its high barrier properties toward gas. In addition, an increase of the PC thermal stability and a presevation of the transparency of PC/mica, PC/MXD6 and PC/MXD6/mica films were revealed using mix elements
