CORE-SHELL INORGANIC PARTICLE HAVING GOOD COMPATIBLITY WITH POLYCARBONATE, POLYCARBONATE COMPLEX AND OPTICAL FILM USING THE SAME FOR PLASTIC SUBSTRATE

摘要

Core-shell inorganic particles are provided to ensure good compatiblity with a polymer, low coefficient of thermal expansion, excellent optical property, especially, light transmission. Core-shell inorganic particles with excellent compatibility with polycarbonate have the surface forming core, wherein the surface is modified with polycarbonate or polycarbonate precursor. The inorganic particles forming core is selected from the group consisting of silica, TiO2, ZrO2, MgO, SiC, Al2O3 and their mixed metal oxide. The polycarbonate precursor is selected from the group consisting of bisphenol A and bisphenol A-based polycarbonate oligomer.
