Title:
METHOD FOR PRODUCING SILVER NANOPARTICLES HAVING BROAD PARTICLE SIZE DISTRIBUTION, AND SILVER NANOPARTICLES
Document Type and Number:
WIPO Patent Application WO/2018/198810
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing silver nanoparticles having good physical properties, whereby it becomes possible to reduce the discharge amount of an amine having a very irritating odor. [Solution] A method for producing silver nanoparticles, comprising reacting a silver compound (a) having thermal degradability with an amine compound (b) capable of forming a complex with the component (a) to form a complex and then thermally degrading the complex by heating to form the silver nanoparticles, said method being characterized in that the component (b) is an amino alcohol having 6 or less carbon atoms and also having one primary or secondary amino group and one hydroxyl group. Silver nanoparticles having an average particle diameter of 350 nm or less and a coefficient of variation of 40 to 80%, wherein an amino alcohol having 6 or less carbon atoms and also having one primary or secondary amino group and one hydroxyl group is bonded to the surface of each of the silver particles.
