The main subject of this thesis is the physics of spin glasses. After their introduction in the 70s in order to describe dilute magnetic alloys, spin-glass models have...

Filled rubbers were prepared using radical polymerization. Colloids used are monodisperse and spherical, their surface is functionalized with silane creating covalent...

The aim of the thesis was to elucidate the effect of confinement of amorphous phase of apolymer above its glass transition temperature being in contact with another...

This thesis deals with the dynamical nature of the glass transition. In a first part, we study a class of mean field spin glass models. We show that the nature of the...

Miscible polymer blends of Polybutadiene (PB) and Styrene Butadiene Rubber (SBR) are studied in order to relate their microscopic structure to their macroscopic linear...

This work forms part of a project aimed to develop Polyamide 6,6(PA6,6)-based automotive fuel tanks. PA6,6 is a good candidate for technical applications since it...

The aim of this work is to understand the influence of silica nanoparticles on the physical transitions of different polymer matrix : polyfurfuryl alcohol (PFA),...

This thesis is devoted to the theoretical study of the transition towards the amorphous solid state. Amorphous solids can be divided into two categories: those that...
