The surface of nano silicon dioxide was modified by silane coupling agentto produce vinyl. Then glycidyl methacrylate (GMA) monomer was grafted to modified nano silicon dioxide by use of γ-irradiation. Effects of monomer concentration and irradiation dose on the grafting yield were studied. It was found that for simultaneous irradiation method, the reaction conditions had a complex effect on grafting yield. Fourier Transform Infrared Spectroscopy(FT-IR), Simultaneous Thermal Analysis (TGA), Transmission Electron Microscope (TEM) had been characterized the composition and structure of grafted nano silicon dioxide.
