METHOD FOR PRODUCING COMPOSITE PARTICLE DISPERSION LIQUID, COMPOSITE PARTICLES, AND METHOD FOR PRODUCING METALLIC NANOPARTICLE DISPERSION LIQUID

摘要

Provided are: composite particles in which the rate at which metallic nanoparticles cover the surface of each dielectric particle is higher than that of conventional art; a method for producing a composite particle dispersion liquid with which it is possible to produce said composite particles; a composite including said composite particles; and a method for producing said composite. This method for producing a composite particle dispersion liquid comprises a step for producing a metallic nanoparticle dispersion liquid including negatively charged metallic nanoparticles, and a step for mixing said metallic nanoparticle dispersion liquid and a dielectric particle dispersion liquid including positively charged dielectric particles, wherein said step for producing said metallic nanoparticle dispersion liquid involves: preparing a liquid including metallic ions and a conjugate base of malic acid and/or isocitric acid; producing metallic nanoparticles by reducing the metallic ions in said liquid; and substituting said conjugate base of malic acid and/or isocitric acid in said liquid with a conjugate base of citric acid.
