Abstract

Homogenously dispersed TiO₂/poly(methyl methacrylate) (PMMA) composite microspheres were produced in the size range of 1-10μm and the interfacial characteristics of TiO₂ and PMMA in suspension polymerization were considered. In electron microscopy observation, it was found that TiO₂ nanoparticles were embedded homogeneously in the PMMA phase. This study elucidates that the interfacial compatibility between TiO₂ and PMMA played a decisive role in producing the composite microspheres structured with inner TiO₂ and continuous PMMA, which was achieved by treating the surface of the TiO₂ particles hydrophobically. The TiO₂/PMMA composite microspheres produced showed good ability to protect against UV rays and are therefore of great usefulness in cosmetic formulations.
