MANUFACTURING METHOD OF CONDUCTIVE PARTICLE, AND CONDUCTIVE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide conductive compound particles in which the surface of a metal oxide particle is decorated by metal colloid particles, and its manufacturing method.

SOLUTION: This is a manufacturing method of a conductive compound particle in which a metal oxide particle (A-1) dispersion liquid surface-treated by an amino group-contained silane compound and a metal colloid particle (M-1) dispersion liquid surface-treated by a carboxyl group and/or a carboxylate group-contained organic compound are mixed. This is a manufacturing method of a conductive compound particle in which a metal oxide particle (A-2) dispersion liquid surface-treated by a sulfhydryl group-contained silane compound and a metal colloid particle (M-2) dispersion liquid are mixed. The conductive compound particle has the surface of the metal oxide particles (A) covered with the metal colloid particles (M), and the average particle size (DA) of the metal oxide particles (A) is 0.1-3μm and the average particle size (DM) of the metal colloid particles (M) is 1-100 nm.
