Title:
METHOD FOR PRODUCING SILVER NANOPARTICLES, SILVER NANOPARTICLES, AND SILVER COATING COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2013/105530
Kind Code:
A1
Abstract:
Provided are: silver nanoparticles which have excellent stability and develop excellent conductivity when fired at low temperatures; a method for producing the silver nanoparticles; and a silver coating composition which contains the silver nanoparticles. A method for producing silver nanoparticles, which comprises: a step of preparing an amine mixed solution that contains (A) an aliphatic hydrocarbon monoamine, which is composed of an aliphatic hydrocarbon group and one amino group, and wherein the total number of carbons in the aliphatic hydrocarbon group is 6 or more, (B) an aliphatic hydrocarbon monoamine, which is composed of an aliphatic hydrocarbon group and one amino group, and wherein the total number of carbons in the aliphatic hydrocarbon group is 5 or less, and (C) an aliphatic hydrocarbon diamine, which is composed of an aliphatic hydrocarbon group and two amino groups, and wherein the total number of carbons in the aliphatic hydrocarbon group is 8 or less; a step of mixing a silver compound and the amine mixed solution, thereby producing a complex compound that contains the silver compound and the amines; and a step of thermally decomposing the complex compound by heating, thereby forming silver nanoparticles.
