Cesium tungstate powder for preparation of nano heat insulating coating can be Cs0.33WO3 nano powder with high near-infrared (NIR) shielding ability. While due to high photothermal conversion efficiency of Cs0.33WO3, the absorbed solar energy may overheat the window glasses, decreasing their transparent heat-insulation performance. To solve this problem, the experts design a new composite window by integrating Cs0.33WO3 with paraffin wax (a phase change material).
