Nano tungsten trioxide has been employed in the production of office building thermal insulating glass coating in recent years. And the coating film formed on the glasses of office building allows the user to changing the amount of heat or light passing through. It has been reported that nano tungsten trioxide is an ultraviolet shielding nanomaterial, which can be combined with near-infrared long-wave shielding nanomaterial and near-infrared short-wave shielding nanomaterial to form a high-performance transparent office building thermal insulating glass coating.

Nano tungsten trioxide has been widely studied over the past few decades. For example, the experts use the tungsten trioxide nanoparticles as the functional material for producing balcony thermal insulating glass coating, so that the prepared smart coating can exhibit a good heat insulation effect with high transparency, high hardness and many other advantages.

Nano tungsten trioxide is frequently applied for preparing study thermal insulating glass coating. And the prepared coating is a kind of hi-tech heat shielding material which can shield 99% of ultraviolet rays and most of infrared rays. While the study thermal insulating glass coating of nano tungsten trioxide is not yet able to fully shield all ultraviolet and near-infrared. So, is there any material that can realize this function?

Cesium tungsten bronze for producing glass curtain wall thermal insulating glass coating is a new high-tech material with excellent infrared absorption performance. At present, the hydro/solvothermal method has attracted wide attention as it can prepare cesium tungsten bronze nanorods with excellent thermal insulation properties.
