A Preparation Method of CsxWOyFz Film

According to the experts, 0.3g of F-doped cesium tungsten bronze powder was dispersed in water. After ultrasonic vibration, the prepared dispersion was added into a PVA solution and heated in a water bath to obtain a F-doped cesium tungsten bronze coating. Then, the obtained coating is coated on a glass sheet by a roll coating method to obtain a CsxWOyFz film. And it was found that such a film is a heat insulation film with excellent heat shielding properties and high transparency.
