Modified SiO_2 nanoparticles were filled into polycarbonate (PC) by two different methods. In order to enable the inorganic nanoparticles dispersed evenly in the PC matrix, the silane coupling agent KH-550 was used to modify the surface of SiO_2 nanoparticles by wet treatment. The relationships between mechanical and processing properties of PC/SiO_2 composite and silica content were examined, and product performance characterized. The characteristics of rigid modified inorganic nanoparticles filled on a typical engineering plastic PC were also studied to explore the mechanism of its strength enhancement and the rheological properties of PC/SiO_2 composite. The results show that the modified SiO_2 spheres had uniform dispersion in PC matrix and PC/SiO_2 composite had good tensile strength and rheological effect.
