Cesium doped tungsten oxide nanopowder may be directly applied for producing window heat insulation film. And the nano grain size cesium doped tungsten oxide may be prepared into heat insulating coating and then be sprayed in the building window glass to obtain heat insulating thin film.

Cesium doped tungsten oxide nanopowder may be applied for producing heat insulation coating. And the prepared coating is an environmentally friendly nano transparent thermal shielding coating designed to absorb infrared and ultraviolet light from sunlight. The nano transparent thermal insulation coating is also a new water-based coating that meets the requirements of environmentally friendly coating.

Cesium doped tungsten oxide nanopowder may be prepared into nano transparent thermal insulation coating, and then be applied to architectural glass to obtain thermal insulating glass. Such glass can block ultraviolet and near-infrared rays in sunlight. In other words, it can achieve heat insulation and anti-UV effect. Specifically, the construction process of the nano transparent heat insulating coating is as follows: surface cleaning, drying, coating, standing, and drying.

Cesium doped tungsten oxide nanopowder may be used for producing thermal insulation coating. The obtained coating is a transparent thermal insulation material with the performance of shielding near-infrared rays, which is widely used for thermal insulation of automobile and architectural glass. In recent years, it has been found that cesium doped tungsten oxide, i.e., cesium tungsten bronze, has excellent near-infrared absorption property, can absorb infrared rays of less than 1500nm, and has high visible light transmittance, so it has a large demand.
