Abstract:

The vibration damping property of plant fibres composites is of practical interest for commercial applications of biobased and eco-composites. Damping behaviour has been observed by experimentation and exploited in the marketing of sporting equipment but the origins of this behaviour have so far been only based on conjectures. In this thesis, the damping capacity of plant fibre composites was attributed to their chemical composition and the reversible interactions enabled by the breaking and reforming of hydrogen bonds under stress. The approach to explaining the mechanisms started with the ch

Abstract:

Porous inorganic materials that can be used in applications such as catalysis and separations have been intensely studied due to their potential stability, ease of recovery and high surface areas. Organic-inorganic hybrid materials meet these criteria by exploiting the physical robustness of porous inorganic materials and the chemical functionality of organic materials. While amorphous oxides are widely used industrially as inorganic supports, disordered pore structures make them difficult to characterize. Ordered-mesoporous-silica (OMS), such as SBA-15, that have ordered pores structures simp

We present the synthesis and characterisation of novel single organic molecules known as phenoxylene borazines and borazatruxenes. Using temperature-dependant and concentration-dependant 1H NMR, we probe the supramolecular aggregation of these molecules in solution. Finally, we synthesise 2D hybrid material comprised of electron delocalised benzene rings and electron localised borazine rings. Using a combination of solid-state 11B and 13C NMR techniques, Raman spectroscopy and XPS, we confirm the presence of benzene and borazine regions in these novel materials.

The size/shape dependent and unique physical and chemical properties presented by nanostructured materials have attracted great attention in several fields such as energy harvesting, optoelectronics and biomedicine, among others. Even though binary semiconductors have been some of the most studied systems until now, ternary and quaternary semiconductors have started to stand out due to the wide variety of compositions and, as a result, of properties they offer. The importance of hybrid nanomaterials is growing as well: the association of more than one material in the same nanostructure usually

Abstract:

La chimie d'interface du diazonium a progressé au cours des dernières années et s'est pratiquement impliquée dans tous les domaines de la science et technologie des matériaux. L’utilisation des sels de diazonium est justifiée par le fait qu’ils adhèrent aux surfaces avec de fortes énergies de liaison, en particulier sur le carbone sp², ce qui en fait d’excellents agents de couplage pour les polymères aux surfaces. Dans ce contexte, nous avons travaillé sur deux types de nanohybrides de nanotubes de carbone (NTC) : NTC-polytriazole (NTC-PTAz) et NTC-colorant. Le nanohybride NTC-PTAz a été synth

Abstract:

This diploma thesis examines the effect of short fiber reinforcement in particle composite with a polymer matrix and the effect of its structure on the mechanical properties. It studies the refraction toughness depending on the addition of short polyvinylalcohol fibers (PVAL), nanosilica and pulverized polymethylacrylate (PMMA) to a dimethylacrylate matrix. Matrix strengthening was characterised with the help of differential compensation photocalorimetry. The inner structure of the composite and the morphology of fracture were studied using a scanning electron microscope. For the tested sample

Cette thèse est consacrée à la synthèse de peptides hybrides possédant un ou plusieurs groupements silanes et à leurs utilisations pour la conception de matériaux hybrides. Deux types de peptides hybrides silylés ont été mis au point : les peptides triethoxysilanes et chloro diméthylsilanes.La première partie de ce manuscrit présente la synthèse de peptides triethoxysilanes, ligands de récepteurs surexprimés dans certains types de cancer. Ils ont été utilisés pour la multi fonctionnalisation de nanoparticules de silice fluorescentes obtenues par voie sol-gel. Une méthode originale de caractéri
