Cs Doped Tungsten Oxide Nanopowder Applied for Infrared Thermal Insulation Nano Material

Cs doped tungsten oxide nanopowder may be applied for preparing infrared thermal insulation nano material such as a new transparent thermal insulation coating. And the prepared coating has the characteristics of uniform dispersibility, good stability and excellent near-infrared performance. So, how is it that a coating has made into a film?

The coating of cesium doped tungsten oxide nanoparticles can be formed into a transparent film by spraying techniques. The basic principle of the spraying process is to place the coating in a nebulizer and spray the coating liquid onto a selected substrate to form a film under a certain pressure. Therefore, there is a high requirement for uniformity in the atomization of the coating into droplets, which will directly affect the performance of the prepared film. During the spraying process, the atomized droplets can be uniformly coated onto the substrate by ultrasonication. In addition, it is also possible to apply a strong airflow pressure to the coating by using a spray gun to generate atomized droplets, which can quickly perform film coating work and has high utilization rate of the coating. However, the implementation of spraying process requires high equipment and low construction universality.
