It is shown that polystyrene has been grafted on the surface of nmSiO2 particles and the grafting ratio is about 40%. The surface of nmSiO2 could be treated effectively by KH570in absolute ethanol at 25℃, 48h. The nmSiO2-g-PSt unpurified by toluene appear microsphere in which nmSiO2 particles are contained, whereas the purified one appear internet formed by many pieces. The grafting ratio of PSt on nmSiO2 surface could be influenced obviously by dispersion agents content and agitation speed, whereas the morphology of nmSiO2-g-PSt purified is rarely changed.
