摘要

This paper presented a method for modifying potassium titanate whiskers (K₂O·6TiO₂) to obtain polymethyl methacrylate (PMMA)/K₂O·6TiO₂ composite particles through emulsion polymerization. The effects of reaction time, initiator concentration, monomer concentration and reaction temperature on the efficiency of conversion or percentage of weight gain were investigated in details. The optimal conditions to reach high conversion efficiency were found. According to the characterization of TGA and SEM, the potassium titanate whiskers were modified through covering PMMA on their surfaces. The characterization of dynamic wetting capacity showed that K₂O·6TiO₂ was modified from hydrophilic to hydrophobic states.
