Composite composition of inorganic oxide particles and silicone resin, method of manufacturing the same, transparent composite, and method of manufacturing the same

摘要

A method of manufacturing a composite composition, having: bonding a dispersant to the surfaces of inorganic oxide particles to provide dispersibility in a hydrophobic solvent to the inorganic oxide particles, and then dispersing the inorganic oxide particles in a hydrophobic solvent; substituting the dispersant bonded to the surfaces of the inorganic oxide particles with a surface modifier, which is a polydimethylsiloxane-skeleton polymer having one functional group at one terminal end, in the hydrophobic solvent in which the organic oxide particles are dispersed to bond the functional group of the polydimethylsiloxane-skeleton polymer to the surfaces of the inorganic oxide particles; and conjugating a silicone resin and the inorganic oxide particles obtained in the previous step, wherein the surface thereof is modified by bonding the polydimethylsiloxane-skeleton polymer having one functional group at one terminal end thereof, to obtain a composite composition.
