Nano cesium doped tungsten oxide may be applied for preparing thermal insulation film. And such heat insulation film can be prepared by the following steps: fully grinding and ultrasonically dispersing the cesium doped tungsten oxide nano powder in a citric acid solution, and then adding it to a 0.1g/mL polyvinyl alcohol solution. Then, the mixture was stirred in a water bath at 80°C for 30min, aged 1-2d to obtain a latex to be coated, and a film was prepared on a glass slide by a dip-drawing method.

Nano cesium doped tungsten oxide may be applied for producing transparent thermal insulation material. With the promotion of the heat insulation material, the preparation of cesium doped tungsten oxide powder is also more important. In this regard, experts have proposed a method for preparing Cs doped tungsten oxide powder by the following steps:

Nano cesium doped tungsten oxide may be applied for preparing transparent thermal insulation nanopowder. And the powder structure and near-infrared absorption characterization are of great reference value for knowing about its near-infrared shielding performance.

Cesium doped tungsten oxide may be made into thermal insulation film for applying in heat insulating window glass. According to experts, the thermal insulation film components have the following weight percentages: 25-30% of the main photochromic material, 70-75% of the auxiliary photochromic material, and the balance water; Wherein, the main photochromic material is tungstic acid, and the auxiliary photochromic material is polyvinylpyrrolidone.
