Study on Surface Modification of Titanium Dioxide Using Polymethyl Methacrylate

摘要

The polymerization of methyl methacrylate (MMA) at the surface of titanium dioxide (TiO_2) par- ticles 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.
