Abstract:
An organic-inorganic composite material which comprises a matrix of an organic polymer (E) which has a backbone composed of polycarbonate, polyarylate, or polysulfone; metal oxide particles (C) dispersed uniformly in the organic polymer (E); and a surface modifier for allowing the metal oxide particles (C) to disperse uniformly in the organic polymer (E),wherein the surface modifier is derived from an organic polymer (A) which has a metal alkoxide group and a backbone of the same kind as the organic polymer (E), and, in the surface modifier, a backbone of the organic polymer (A) being bonded covalently to the metal oxide particles as a result of a condensation reaction between the metal alkoxide group and the metal oxide particle.
