Cs0.33WO3 Near Infrared Shielding Material

Cs0.33WO3 near infrared shielding material refers to the thermal insulating material prepared by using functional particles of cesium tungsten bronze as a raw material. These materials are mostly highly transparent architectural glass thermal insulation materials, which are more and more widely applied in glass curtain walls, sunlight rooms and many other glass buildings with good heat insulation effect and broad application prospects. Some experts studied the effect of Cs0.33WO3 particle concentration, ball milling and dispersing agent on the dispersion stability of the obtained heat insulation materials.

Experts have found that Cs0.33WO3 particles still have good dispersion stability after its concentration is increased to 11.54%. Although the highest visible light transmittance is the approximation of before ball milling, the transmittance of the near-infrared rays is sharply reduced to 5% at 1100nm. The excellent near-infrared shielding performance is manifested after ball-milling and the addition of the dispersing agent, so the dispersed and stable Cs0.33WO3 particles can be uniformly distributed on the surface of the coating to form a continuous shielding layer to prevent the transmission of near-infrared light.
