High-performance coatings that durably and fully repel liquids are of interest for fundamental research and practical applications. Such coatings should allow for droplet beading, roll off and bouncing, which is difficult to achieve for ultralow surface tension liquids. Here we report a bottom-up approach to prepare super-repellent coatings using a mixture of fluorosilanes and cyanoacrylate. On application to surfaces, the coatings assemble into thin films of locally multi-re-entrant hierarchical structures with very low surface energies. The resulting materials are super-repellent to solvents, acids and bases, polymer solutions and ultralow surface tension liquids, characterized by ultrahigh liquid contact angles (>150°) and negligible roll-off angles (~0°). Furthermore, the coatings are transparent, durable and demonstrate universal liquid bouncing, tailored responsiveness and anti-freezing properties, and are thus a promising alternative to existing synthetic super-repellent coatings.

持久且完全排斥液体的高性能涂料对于基础研究和实际应用非常重要。这种涂层应允许液滴成珠，滚落和弹跳，这对于超低表面张力的液体很难实现。在这里，我们报告了一种自下而上的方法，该方法使用氟硅烷和氰基丙烯酸酯的混合物来制备超疏水涂层。在应用于表面时，涂层会组装成具有非常低的表面能的局部多凹入分层结构的薄膜。所得材料对溶剂，酸和碱，聚合物溶液和超低表面张力液体具有超强排斥性，其特征在于超高液体接触角（> 150°）和可忽略的滚落角（〜0°）。此外，涂层是透明的
