METHOD FOR PRODUCING SILVER NANOPARTICLES, SILVER NANOPARTICLES, AND SILVER COATING COMPOSITION |
摘要 |
The present invention provides silver nano-particles that are excellent in stability and develop excellent conductivity by low-temperature calcining, a producing method for same, and a silver coating composition comprising the silver nano-particles. A method for producing silver nano-particles comprising: preparing an amine mixture liquid comprising: an aliphatic hydrocarbon monoamine (A) comprising an aliphatic hydrocarbon group and one amino group, said aliphatic hydrocarbon group having 6 or more carbon atoms in total; and an aliphatic hydrocarbon monoamine (B) comprising an aliphatic hydrocarbon group and one amino group, said aliphatic hydrocarbon group having 5 or less carbon atoms in total, in a ratio wherein the amine (A) is 5 mol % or more and less than 20 mol % and the amine (B) is more than 80 mol % and 95 mol % or less, based on a total of the amine (A) and the amine (B); mixing a silver compound and the amine mixture liquid to form a complex compound comprising the silver compound and the amines; and thermally decomposing the complex compound by heating to form silver nano-particles. |
