Nano transparent heat insulating glass coating of WO3 nanoparticles is a new type of smart material with high heat insulating performance and high heat preservation performance. Such energy efficient coating will form a thin transparent heat-insulating film on the architectural glass. Under ultraviolet or sunlight, the film will change with the intensity of the light, and the color of the film will become darker or lighter, so in a certain space, the automatic adjustment of light intensity is always at an appropriate level.

Nano transparent heat insulating glass coating of yellow tungsten oxide nanoparticles can be applied to the surface of the building glass. And the formed film has high definition and excellent anti-infrared performance. Certainly, yellow tungsten oxide nano particles can also be used to produce automotive films, architectural films and agricultural films, to play the role of high heat insulation, energy conservation, anti-aging and ultraviolet protection.

Nano transparent heat insulating glass coating of tungsten oxide nanoparticles is a new type of self-cleaning heat-insulating glass coating. Such thermal insulating coating utilizes the principle of hydrophilicity to provide a self-cleaning effect. Generally, the coating acts on the surface of a glass substrate such as building glass and automotive glass.

Tungsten trioxide nanoparticles may be used to prepare a new type of nano transparent heat insulating glass coating, and the prepared coating is environmentally-friendly, energy-saving, safe and non-toxic. Therefore, the smart coating is increasingly used in glass doors and windows of buildings.
