Nano cesium tungsten oxide is a dingal material that can shield ultraviolet rays and near-infrared rays, and thus can be used to manufacture window heat insulation film. The cesium tungsten oxide nanopowder is in the form of transparent heat insulation film on the building glass. This kind of window film may be made of several layers of heat insulation films designed to capture infrared light, preventing it from filtering through to the room. Thus, the window heat insulation film is…
