Title:
COATED INORGANIC FINE PARTICLE AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/017305
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: a coated inorganic fine particle suitable for use as a transparent nanocomposite material in optical members, electronic components, coating materials, dental materials, and the like; and a method for producing the coated inorganic fine particle. Provided is a coated inorganic fine particle which has a coating layer and is obtained by reacting at least one among compounds represented by formulae (A-1), (A-2), (B-1), (B-2), (C), (D-1), and (D-2), and salts thereof on the surface of an inorganic fine particle, wherein the inorganic fine particle has an average particle size of at least 1 nm and less than 100 nm, a specific surface area of at least 1 m2/g and less than 3,000 m2/g, and a volatile organic compound content of less than 100 ppm. According to the present invention, a transparent nanocomposite material which is excellent for mass production, and in which inorganic fine particles are uniformly dispersed without aggregation even at high concentrations, can be obtained.
