Compréhension des phénomènes interfaciaux dans les composites à base de charges carbonate de calcium précipité : influence du traitement de surface et du procédé de mise en œuvre

Abstract : The aim of this PhD work is to elaborate composites based on calcium carbonate nanoparticles. Polylactide and polyvinylidene fluoride were used as polymer matrix and nanocomposite were elaborated either by melting process and either by casting method. The interfacial behaviour between polymer and calcium carbonate were studied and we especially focused on their impact on the composite gas barrier properties. The importance of filler surface treatment had been highlighted on the filler dispersion state improvment and filler/polymer interface reinforcement. Both parameters were important in the improvement of composite gas barrier properties.
