METHOD FOR PRODUCING ORGANICALLY MODIFIED INORGANIC FINE PARTICLE AND ORGANICALLY MODIFIED INORGANIC FINE PARTICLE
The present invention enables organically modifying a starting particle with a variety of molecular structures, such as AlN, TiN, Si3N4, or SiC, uniformly on the entire surface of the starting particle using a common method to easily provide an organically modified inorganic fine particle with further improved dispersibility in a solvent.The present invention is a method for producing an organically modified inorganic fine particle. The method includes: forming an oxide layer, an oxyhydroxide layer, and/or a hydroxide layer on a surface of at least one or more kinds of starting particle selected from inorganic nitrides, inorganic carbides, inorganic sulfides, and insoluble salts; and organically modifying the starting particle, on which the oxide layer, the oxyhydroxide layer, and/or the hydroxide layer is formed, in a reaction field of a supercritical, subcritical, or gas phase aqueous solvent to obtain an organically modified inorganic fine particle.
