Cesium Tungsten Oxide Applied for Transparent Heat Insulation Coating

Cesium tungsten oxide is mainly applied for manufacturing transparent heat insulation coating to show good visible light transmittance and excellent near-infrared shielding properties. And the cesium tungsten oxide coating is thin and transparent with the advantages of energy conservation and environmental protection when it is applied to a glass substrate.

It is reported that some experts have prepared Cs0.33WO3 coating with PVA, PVB and PVP as film former, respectively. And these experts investigated the influence of ball-milling and dispersant on the dispersion stability of Cs0.33WO3 particles and its near infrared shielding properties to obtain good dispersion of Cs0.33WO3 particles and improve their near-infrared shielding efficiency. The results indicated that ball-milling and polyethylene glycol-400 could decrease the particles size of Cs0.33WO3 and improve its dispersion stability. The coating of PVA/Cs0.33WO3 and PVP/Cs0.33WO3 showed the best visible light transmittance and near-infrared shielding properties, while PVB/Cs0.33WO3 coating showed excellent adhesion.
