In this work, a complete process for preparation of SiO₂/Cs_0.32WO₃ composite coatings with superhydrophobic and NIR shielding properties has been proposed. Combined nano-porous SiO₂ with the spectral selective Cs_0.32WO₃, the composite coating could not only show excellent heat blocking property but also possess self-cleaning performance. In the simulated contaminant experiment, almost all of dust particles on the surface of composite coating could be picked up by the rolling droplets, and the water contact angle of the coating was up to 160°. The thermal shielding experiment proved that the SiO₂/Cs_0.32WO₃ composite coating could effectively reduce more than 20% room temperature in the same irradiation time. Furthermore, the energy consumption simulation shows that comparing with normal glass, the SiO₂/Cs_0.32WO₃ coated glass could save about 15.9% total electrical consumption per year in Guangzhou, which is even superior with that of low-e glass.

在这项工作中，已提出了制备具有超疏水和近红外屏蔽性能的SiO ₂ / Cs _0.32 WO ₃复合涂层的完整方法。将纳米多孔SiO ₂与光谱选择性Cs _0.32 WO _{3结合使用}，复合涂层不仅表现出优异的隔热性能，而且具有自清洁性能。在模拟的污染物实验中，复合涂层表面上几乎所有的灰尘颗粒都可以被滚动的液滴吸收，并且涂层的水接触角高达160°。热屏蔽实验证明SiO ₂ / Cs _0.32 WO ₃复合涂层可以在相同的照射时间内有效地降低超过20％的室温。此外，能耗模拟结果表明，与普通玻璃相比，SiO ₂ / Cs _0.32 WO ₃涂层玻璃每年可节省广州约15.9％的总电耗，甚至优于低辐射玻璃。
