Abstract :
In recent years, polymer/inorganic nanocomposites have already attracted the interests. In this paper, EVA/inorganic nanocomposites of direct-dispersed, one-step and two-step were prepared by melt blending. The preparation, morphological Structure and mechanical properties of these composites were systematically investigated, which laid the foundations for the further experimental. The dispersibility of nanoparticles in EVA matrix was characterized by FESEM and FT-IR In all the composite systems, one-step improves the mechanical properties more than direct dispersed and two-step methods; Proper filling of nanoparticles by one-step may decrease the apparent viscosity of the systems; There has a interface bonding layer between EVA and nanoparticles by Vinyl Triethoxyl Silane coupling agent, adjusting the bonding structure between phases; nanocomposites have nano-scale dispersions.
