Cesium Tungsten Oxide Applied for Energy Efficient Glass

Cesium tungsten oxide for preparing energy efficient glass is mainly Cs0.33WO3 nano particles in the form of heat insulation coating. Why choose Cs0.33WO3 nano powder? That is because the energy efficient glass of nano particle size Cs0.33WO3 has high transparency without affecting the daylighting and excellent near-infrared shielding performance to shield the heat radiation in the sunlight.

And it should be noticeable that the dispersion stability of Cs0.33WO3 colloidal solution (for preparing coating) directly affects its optical properties and transparent thermal insulation performance. However, up to now, little research on the dispersion stability of Cs0.33WO3 colloidal solution has been reported. Therefore, some experts investigated the dispersion and stability of Cs0.33WO3 particles, and discussed the effects of solvent and dispersant on the visible transparency and NIR shielding properties of the Cs0.33WO3 coatings. And they found that appropriate dispersant can keep colloidal Cs0.33WO3 dispersion stability through steric stabilization and electrostatic effect.
