In this study, a superhydrophobic coating on glass has been prepared through a single-step aerosol-assisted chemical vapor deposition (AACVD) process. During the process, an aerosolized precursor containing polydimethylsiloxane, epoxy resin, and stearic acid functionalized Al-doped ZnO nanoparticles was deposited onto the glass at 350 °C. X-ray photoelectron spectroscopy, scanning electron microscopy, and atomic force microscopy showed that the precursor was successfully coated and formed a nano/microstructure (surface roughness: 378.0 ± 46.1 nm) on the glass surface. The coated surface had a water contact angle of 159.1 ± 1.2°, contact angle hysteresis of 2.2 ± 1.7°, and rolling off-angle of 1°, indicating that it was superhydrophobic. In the self-cleaning test of the coated surface at a tilted angle of 20°, it was shown that water droplets rolled and washed out dirt on the surface. The stability tests showed that the surface remained superhydrophobic after 120 h of exposure to ultraviolet (UV) irradiation and even after heat exposure at 350 °C. In addition, the surface was highly repellent to water solutions of pH 1–13. The results showed that the addition of the functionalized nanoparticles into the precursor allowed for the control of surface roughness and provided a simplified single-step fabrication process of the superhydrophobic surface. This provides valuable information for developing the manufacturing process for superhydrophobic surfaces.

通过气溶胶辅助化学气相沉积工艺生产 EP/PDMS/SA/AlZnO 涂层超疏水表面

在这项研究中，通过单步气溶胶辅助化学气相沉积 (AACVD) 工艺制备了玻璃上的超疏水涂层。在此过程中，将含有聚二甲基硅氧烷、环氧树脂和硬脂酸功能化的 Al 掺杂 ZnO 纳米颗粒的雾化前体在 350 °C 下沉积到玻璃上。X射线光电子能谱、扫描电子显微镜和原子力显微镜表明，前驱体成功包覆并在玻璃表面形成纳米/微结构（表面粗糙度：378.0±46.1 nm）。涂层表面的水接触角为159.1±1.2°，接触角滞后为2.2±1.7°，滚动偏角为1°，表明它是超疏水的。在倾斜20°的涂层表面的自清洁测试中，结果表明，水滴滚动并冲刷了表面上的污垢。稳定性测试表明，在暴露于紫外线 (UV) 照射 120 小时后，甚至在 350°C 的热暴露后，表面仍保持超疏水性。此外，该表面对 pH 值为 1-13 的水溶液具有高度排斥性。结果表明，将功能化纳米粒子添加到前驱体中可以控制表面粗糙度，并提供简化的超疏水表面的单步制造过程。这为开发超疏水表面的制造工艺提供了有价值的信息。此外，该表面对 pH 值为 1-13 的水溶液具有高度排斥性。结果表明，将功能化纳米粒子添加到前驱体中可以控制表面粗糙度，并提供简化的超疏水表面的单步制造过程。这为开发超疏水表面的制造工艺提供了有价值的信息。此外，该表面对 pH 值为 1-13 的水溶液具有高度排斥性。结果表明，将功能化纳米粒子添加到前驱体中可以控制表面粗糙度，并提供简化的超疏水表面的单步制造过程。这为开发超疏水表面的制造工艺提供了有价值的信息。
