CONDUCTIVE ULTRAFINE COMPOSITE POWDER, PREPARING METHOD THEREOF AND COATING SOLUTION FOR CONDUCTIVE FILM CONTAINING THE SAME

摘要

A conductive composite particle is provided to ensure excellent conductivity, transmittance of a transparent conductive film coated on a substrate, and weather resistance with a wetting method like the spin coating, bar-coating, spray coating, and dipping. A conductive composite particle is coated with the silver, gold, ruthenium, palladium or their alloy component on the surface of the conductive oxide or the non-conductive oxide. The maximum grain size is 200‘“ or less by coating the silver, gold, ruthenium, palladium or their alloy component on the surface of the conductive oxide having 30~150‘“ of the average particle diameter so that the size of the grain on the XRD phase becomes 1~20‘“. The average particle diameter is 0.1~100‘í by coating the silver, gold, ruthenium, palladium or their alloy component on the surface of the non-conductive oxide having 0.1~100‘í of the average particle diameter so that the size of the grain on the XRD phase becomes 1~100‘“.
