Robust superhydrophobic surfaces were synthesized as composites of the widely commercially available adhesives epoxy resin (EP) and polydimethylsiloxane (PDMS). The EP layer provided a strongly adhered micro/nanoscale structure on the substrates, while the PDMS was used as a post-treatment to lower the surface energy. In this study, the depositions of EP films were taken at a range of temperatures, deposition times, and substrates via aerosol-assisted chemical vapor deposition (AACVD). A novel dynamic deposition temperature approach was developed to create multiple-layered periodic micro/nanostructures that significantly improved the surface mechanical durability. Water droplet contact angles (CA) of 160° were observed with droplet sliding angles (SA) frequently <1°. A rigorous sandpaper abrasion test demonstrated retention of superhydrophobic properties and superior robustness therein, while wear, anticorrosion (pH = 1–14, 72 h), and UV testing (365 nm, 3.7 mW/cm2, 120 h) were carried out to exhibit the environmental stability of the films. Self-cleaning behavior was demonstrated in clearing the surfaces of various contaminating powders and aqueous dyes. This facile and flexible method for fabricating highly durable superhydrophobic polymer films points to a promising future for AACVD in their scalable and low-cost production.

通过气溶胶辅助化学气相沉积将简单的商用胶水转变为高度坚固的超疏水表面
合成了坚固的超疏水表面，作为广泛可商购的粘合剂环氧树脂（EP）和聚二甲基硅氧烷（PDMS）的复合材料。EP层在基材上提供了牢固粘附的微米/纳米级结构，而PDMS用作后处理以降低表面能。在这项研究中，通过气溶胶辅助化学气相沉积（AACVD）在一定温度，沉积时间和基材范围内进行了EP膜的沉积。开发了一种新颖的动态沉积温度方法来创建多层周期性的微/纳米结构，从而显着提高了表面机械耐久性。观察到的水滴接触角（CA）为160°，而水滴滑动角（SA）经常小于1°。2，120 2H）进行了表现出的膜的环境稳定性。在清除各种污染性粉末和水性染料的表面时，证明了自清洁行为。这种用于制造高度耐用的超疏水性聚合物薄膜的简便灵活的方法指出了AACVD的可扩展且低成本的生产前景广阔。
