Cesium Doped Tungsten Oxide Applied for Heat Insulation Coating

Cesium doped tungsten oxide may be applied for preparing heat insulation coating, which can be applied to glass to form a heat insulating film. According to experts, the obtained thermal insulation thin film can shield ultraviolet rays and near-infrared rays.

While how to operate specifically? According to experts, the main steps need to be achieved: disperse the Cs doped tungsten oxide powder in toluene, add 0.1mm zirconium beads to the three-roller machine, then add a small amount of acetic acid to catalyze, and then add the modifier HDTMS. The reaction is carried out at 80°C for 8 hours to obtain doped tungsten oxide nano slurry, and then PSA is mixed and applied to PET to obtain the heat insulation film of Cs doped tungsten oxide.

In this regard, experts said that the near-infrared light absorption will increase with the adding of Cs doped tungsten oxide powder. And its excellent near-infrared shielding effect is 67% and 86% at 5% and 7%, respectively. In addition, a PET film with a solid content of 7% of Cs doped tungsten oxide can absorb light energy and convert it into heat energy under light irradiation, and then transfer heat to the surrounding medium for tens of picoseconds to make the temperature buffer effect reaches 5.8°C, which has strong application potential in the field of heat insulation.
