Fabrication of thermochromic composite films using transition temperature controlled VO2 fine particles
Source abstract
Abstract
A vanadium oxide based precursor fine powder was prepared by the reaction of vanadium metal and W-IPA H2O2 aqueous solution, and non-doped VO2 or W-doped VO2 fine powder was obtained by heat-treatment of the precursor powder at 650°C in an H2/Ar atmosphere. Composite films were fabricated using the non-doped or W doped VO2 fine powder and transparent urethane resin. The resulting composite films showed a reversible thermochromic property. The transition temperature of the composite using non-doped VO2 powder was 68.9°C, and that of the composite using 1% W doped VO2 powder was 46.3°C.
