Abstract

See full text

A vanadium dioxide coating for intelligent temperature control is formed by mixing a vanadium dioxide powder slurry, a polymer emulsion, and coating additives, and then coating the mixture onto a substrate. The vanadium dioxide powdery slurry comprises vanadium dioxide composite powders and a dispersion medium, the composite powders comprising vanadium dioxide nanopowders having a chemical composition of V1−xMxO2, and the surface of the vanadium dioxide nanopowders being attached to organic modified long-chain molecules, wherein M is a doped element, and 0≦x≦0.5. Through using the vanadium dioxide powders and the slurry thereof having an organic modified surface, the coating has higher visible light transmittance, can almost completely screen ultraviolet rays, and simultaneously intelligently adjust infrared rays.
