Violet tungsten oxide may be used to produce nano transparent heat insulating glass coating, which is a type of smart glass heat insulating coating. Such smart coating has been widely applied in building energy-saving renovation to play the role of heat insulation, energy conservation and consumption reduction. And therefore the heat insulating coating of violet tungsten oxide nanoparticles is deeply loved by the public.

Violet tungsten oxide nanopowder is an inorganic nano powder with surface and interface effects, small size effect and macroscopic quantum effect so that it may be prepared into a composite material with resin to obtain a nano transparent heat insulation coating, And therefore the coating prepared have special functions, such as high heat insulation and high UV-resistant property. Also, the violet tungsten oxide nano particles greatly improve the physical and chemical properties of the coating.

Violet tungsten oxide nanopowder may be used to prepare an energy saving glass coating with the advantages of high visible light transmittance, strong infrared and ultraviolet shielding performance, excellent anti-aging performance, high cost performance and environmental protection. Therefore, the thermal insulation coating of nano particle size violet tungsten oxide for applying to smart glass has become a research hotspot of many domestic and foreign scientific research workers in recent years.

Violet tungsten oxide nanopowder may be prepared into thermal insulation dispersion for producing thermal insulation coating, and then the coating obtained may be applied to the architectural glass to obtain energy efficient building glass. Among them, in the production process of the coating, it has a great influence on the heat-insulating effect of the smart glass to choose a film-forming material.
