SILOXANE STAR-GRAFT POLYMER, CERAMIC POWDER COATED THEREWITH AND METHOD OF PREPARING COATED CERAMIC POWDER

摘要

PPROBLEM TO BE SOLVED: To provide ceramic powders coated with a polymer having a controlled fractal property. PSOLUTION: The coated ceramic powder comprises a plurality of ceramic particles and a siloxane star-graft coating polymer encapsulating at least a portion of the particles. The coating polymer comprises Si(w, x, y, z), where w, x, y and z are the mole percent tetrafunctional, trifunctional, difunctional and monofunctional monomeric units, respectively, and wherein w is about 45-75 and x, y and z are about 5-25, and 5-10, respectively.
