Cs0.33WO3 infrared thermal insulation nano material can be a cesium tungsten bronze architectural thermal insulation coating. Some experts compared the near-infrared shielding performance of Cs0.33WO3 coating with the near-infrared shielding performance of several thermal insulation coatings on the market. The figure below shows the transmittance spectra of Cs0.33WO3 coating compared with transparent heat insulation coatings and Low-E glass.

Among them, A is a transparent thermal insulation coating produced in China, and B is a transparent heat insulation coating produced in Japan. Due to different pigment concentrations of different transparent heat-insulating coatings, the visible light transmittance is significantly different when the same thickness is applied. The highest transmittance of the three coatings is around 600nm, which has a strong shielding effect on the near-infrared region. Low-E glass has the best visible light transmission performance, but has a low shielding rate in the near-infrared region. Although these heat insulating materials have good transparent heat insulation effect, the high preparation cost is the main reason that restricts their wide application. While the Cs0.33WO3 coating not only has excellent optical properties, but also has environmental protection. And its price is relatively low. That is to say, the application prospect of Cs0.33WO3 coating will be relatively wide.
