Thermochromic fine particles, dispersion thereof, production method thereof, and light control paint, light control film and light control ink

摘要

Thermochromic microparticles including vanadium dioxide (VO2) particles of a rutile crystal phase (R phase), and titanium dioxide (TiO2) particles of the rutile crystal phase (R phase), wherein at least one of the vanadium dioxide (VO2) particles of a rutile crystal phase (R phase) is grown like a rod on the titanium dioxide (TiO2) particles to be larger than sizes of the titanium dioxide (TiO2) particles.
