Title:
A water dispersion of a metal nanoparticle, and a manufacturing method for the same
Document Type and Number:
Japanese Patent JP6008424
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous dispersion of metal nanoparticles, which has practically sufficient dispersibility, and to provide a production method of the dispersion.SOLUTION: The production method of the aqueous dispersion of metal nanoparticles includes: a step for mixing the metal nanoparticles (a) and amines (b) or a step for mixing the metal nanoparticles (a) and a β-1,3-1,6 glucan (c) having a branching degree of the β-1,6 bond to the β-1,3 bond of 50-100% in a solution which is adjusted to alkalinity by using amines (b) as alkali; and a step for neutralizing the resulting mixed solution by the addition of a neutralizer (d).
