Abstract Superhydrophobic surface (SHS) attracted great attention in the field of anti-icing due to its unique superwettability. Herein, SHS was fabricated on aluminum (Al) alloy substrate with a water contact angle of 152.2° and a sliding angle of 3.4° by simple chemical etching and long-alkyl-chain grafting. Anti-icing performances of both static and dynamic water droplets on SHS were investigated. Results demonstrated that SHS delayed the ice nucleation of static water droplet greatly, however, could not suppress the icing of high-speed water droplets.

超疏水表面上静态和高速水滴的结冰

摘要 超疏水表面（SHS）以其独特的超润湿性在防冰领域引起了广泛关注。在此，SHS 是通过简单的化学蚀刻和长烷基链接枝在铝 (Al) 合金基板上制备的，水接触角为 152.2°，滑动角为 3.4°。研究了静态和动态水滴在 SHS 上的防冰性能。结果表明，SHS 大大延迟了静态水滴的冰核形成，但不能抑制高速水滴的结冰。
