Nano grain size cesium tungstate may be applied for preparing thermal insulation film, which is mainly applied to building glass that needs to shield ultraviolet rays and infrared rays. It is reported that this kind of heat insulation film can block harmful rays in sunlight, improve the comfort of living environment, and save energy. In addition, the applicable substrate of such heat insulating material, in addition to transparent glass, is transparent acrylic, transparent PET, and PP.

As you may have known, the metal glass curtain building has the advantages of light weight, shock resistance, rapid construction, and wide landscape. If the problem of air conditioning loss can be solved, it may be the mainstream of high-rise building design in the future. And the nano heat insulation material is environmentally-friendly with excellent heat insulation effect. In other words, it blocks the near-infrared. Also, it has a high ultraviolet blocking ding. In addition, the indoor lighting is not affected, so the material will have a broader application prospect in the future.
