Cesium tungsten oxide such as Cs0.33WO3 is a new type of near infrared shielding material for preparing many transparent heat insulation products such as heat insulation film, heat insulation dispersion, heat insulation coating. And these dingal products are mainly applied to exterior glass doors, glass curtain wall, and exterior glass windows of buildings and cars. For these applications, it requires cesium tungsten oxide has best near-infrared shielding performance. But how to get such a smart coating?

In the production of thermal insulation coating, it is related to the smallest particle size, good wetting and dispersion properties of the colloidal Cs0.33WO3 particle dispersion. The conclusion is drawn from the transmittance spectra of the as-prepared Cs0.33WO3 coatings from colloidal Cs0.33WO3 dispersion with different pH value. And the experts found that the Cs0.33WO3 coating obtained from dispersion with pH = 7 has best near infrared shielding performance. And these researchers believed that the near infrared shielding material of cesium tungsten oxide is becoming more and more popular with scholars.
