中文简介

在目前的工作中,使用简单的刷涂方法制造了聚四氟乙烯/聚二甲基硅氧烷 (PTFE/PDMS) 复合涂层。PTFE/PDMS涂层兼具超疏水自清洁和辐射冷却功能。复合涂层对水的接触角(CA)为159.3°,对水的滑动角(SA)为6.3°。此外,涂层在200-2500 nm波长范围内的太阳反射率接近92%,在8-13 μm中红外波段的红外发射率约为0.93。当夏季白天最高温度为39℃时,PTFE/PDMS涂层在上午10:00至下午16:00阳光直射下可达到4.73℃的平均辐射冷却温度,在相同条件下,在电动汽车座垫上覆盖PTFE/PDMS涂层可实现座垫温度下降19.41℃。经过50,000 mL模拟酸雨的连续洗涤和腐蚀、10个循环的紫外线(UV)老化实验或25个循环的砂纸磨损后,PTFE/PDMS涂层的超疏水性和辐射冷却功能保持不变。特别是,PTFE/PDMS 涂层在表面被污染后失去了辐射冷却能力。

英文摘要(原文)

surface is contaminated. However, with the help of natural rainfall, its radiation cooling coating could recover rapidly. Therefore, the PTFE/PDMS coating developed in this work makes the radiative cooling coating more practical.
