Abstract

SiO₂ particles were prepared by hydrolysis of ethyl orthosilicate in ammonia/alcohol solution. The SiO₂ particles coated by free radical copolymerization of styrene with MPS. The surface modality, size of the SiO₂ particles, the surface chemical bond of coated particles, surface Zeta potential and dispersion in perchloroethylene was studied by scanning electron microscope (SEM), fourier-transform infrared spectra (FTIR), Zeta potential measurement. It is found that the polystyrene grafted on the surface of SiO₂ particles, Zeta potential was improved from -4.26 mV to -45.73 mV, the response time of academic calculation achieved 183 ms, under electric field which voltage is 9 V. 48 hours after dispersing, dispersion of coated particles was good.
