| 摘 要： | 掺锑二氧化锡(ATO)基透明隔热涂层或贴膜是一种节能新材料,但其表面不耐脏,超疏水化可解决此问题。今在聚二甲基硅氧烷(PDMS)软模板上,采用溶液浇注微模塑法制得了不同ATO含量的ATO/水性聚氨酯(WPU)复合功能膜,其水静态接触角达(151.3±2.1)°,水滴在膜表面极易滚落,同时具有优良的隔热性能和半透明性。扫描电子显微镜(SEM)表征了薄膜表面微结构,发现ATO纳米粒子的加入,使得微米级乳突表面及乳突之间布满纳米级小凸起,这种微米结构和纳米结构相结合的二阶结构,与天然荷叶表面极其相似,是引起隔热薄膜表面超疏水的主要原因。研究结果为规模制备半透明隔热自清洁聚氨酯薄膜提供了理论和实验依据。

| Abstract: | Transparent and thermal insulation coating or film based on antimony doped tin oxide (ATO) nano particle is a new kind of energy-saving material. However, its surface is often contaminated easily, and the surface superhydrophobic modification can solve this problem. In this study, ATO/Polyurethane (ATO/PU) composite film with different ATO% contents were micromolded by casting nanodispersed ATO/waterborne PU suspensions on poly(dimethylsiloxane) (PDMS) templates replicated from fresh lotus leaves.
