Abstract

The isotactic polypropylene – modified silica (iPP/SiO2) hybrid nanocomposites, obtained by grafting polypropylene chains on amine-functionalized silica particles during reactive blending, were studied. It was found that use of amine-functionalized silica and PP-g-MA as a compatibilizer improved dispersion of nanoparticles. Nanosilica, especially surface-modified, revealed some nucleation activity towards iPP, manifesting in an increase of the crystallization temperature and reduction of spherulite size. iPP/silica nanocomposites exhibit highly improved thermo-oxidative stability, due to formation of a silica protective layer, limiting the polymer volatilization rate. Nanocomposites demonstrate enhanced stiffness and strength, but at higher silica content the ductility is nearly lost due to presence of big agglomerates, acting as critical-sized structural flaws. At low silica concentrations dispersion was improved and big agglomerates were not observed. Consequently, iPP/PP-g-MA/am-SiO2 nanocomposites with low silica content demonstrate high ductility and enhanced impact resistance, related to reinforcing effect of well dispersed silica particles.
