Abstract One of the biggest obstacles for superhydrophobic films in applications is their poor mechanical resistance. In this research, robust superhydrophobic SiO2 films were constructed on mild steel (MS) for corrosion protection by the combination of rough electrodeposited SiO2 (E-SiO2) films and durable polydimethylsiloxane (PDMS) polymer with low surface energy. Results show that the PDMS content has a great effect on the microtopography, wettability, roughness, and wear-resistance of the final films. EIS measurements indicate that as-prepared robust superhydrophobic E-SiO2/PDMS films exhibit good corrosion inhibition efficiency of up to 99.99% for MS substrates in 3.5 wt.% NaCl solution.

坚固的超疏水 SiO2/聚二甲基硅氧烷薄膜涂覆在低碳钢上以防止腐蚀

摘要 超疏水薄膜在应用中的最大障碍之一是其机械阻力差。在这项研究中，通过将粗糙的电沉积 SiO2 (E-SiO2) 薄膜和具有低表面能的耐用聚二甲基硅氧烷 (PDMS) 聚合物相结合，在低碳钢 (MS) 上构建了坚固的超疏水 SiO2 薄膜以进行腐蚀保护。结果表明，PDMS 含量对最终薄膜的微观形貌、润湿性、粗糙度和耐磨性有很大影响。EIS 测量表明，所制备的坚固的超疏水 E-SiO2/PDMS 膜在 3.5 wt.% NaCl 溶液中对 MS 基材表现出高达 99.99% 的良好腐蚀抑制效率。
