Abstract

Styrene monomers were grafted onto the surface of the nano-SiO₂ particles via emulsion polymerization after the particles underwent surface pretreatment with silane coupling agent KH-570, for reaching the polymeric coating modification of the particles. The nano-SiO₂ composite particles featuring shell-core structure were prepared in such a way. The surface structure and distribution status in PP matrix of the nano-SiO₂ particles were characterized by Fourier transform infrared spectrometry (FTIR) and transmission electron microscopy (TEM). The results confirm that the modified nano-SiO₂ particles are homogeneously dispersed in the PP matrix and therefore, the mechanical properties of the PP composite material are remarkably improved.
