SILVER NANOPARTICLE, COMPOSITION USING THE SILVER NANOPARTICLE, AND CONDUCTIVE COATING FILM USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a conductive coating film having specific resistance close to that of metal silver by firing at a relatively low temperature, and further, to improve adhesion of the conductive coating film to a base material.;SOLUTION: Each core part of silver nanoparticles with the average particle diameter of 10 to 100 nm is composed of silver particles, the film part of each silver nanoparticle is formed on the whole or a part of the surface of the core part and is made of silver oxide or silver hydroxide. Further, the silver nanoparticles are dispersed into a dispersion medium so as to form a composition. The dispersion medium is alcohols or an alcohols-containing aqueous solution.;COPYRIGHT: (C)2010,JPO&INPIT
