METHOD FOR PRODUCING VANADIUM DIOXIDE-CONTAINING PARTICLES, VANADIUM DIOXIDE-CONTAINING PARTICLES, DISPERSION, AND OPTICAL FILM

摘要

The present invention addresses the problem of providing: a method for producing vanadium dioxide-containing particles, the method being capable of increasing VO₂ content and controlling average particle size and shape; vanadium dioxide-containing particles; a dispersion; and an optical film. The method for producing vanadium dioxide-containing particles produces vanadium dioxide-containing particles that include at least vanadium dioxide (VO₂) having thermochromic properties, and is characterized by forming the vanadium dioxide-containing particles by hydrothermal reaction of a reaction liquid that includes at least hydrophilic macromolecules, a reducing agent, water, and a compound that includes at least vanadium (V).
