| Abstract: | The polymerization of methyl methacrylate (MMA) at the surface of titanium dioxide (TiO 2) particles was carried out by using soapless emulsion polymerization method. In this process, composite particles with TiO 2 core and polymer shell were obtained and thus the surface of titanium dioxide was modified. The encapsulating polymer was characterized by TEM, DTA and IR. In addition, the surface properties of the original and modified TiO 2 were studied by Zeta potential measurement and determination of contact angle and dispersability. |
