Abstract Superamphiphobic surfaces with extreme repellency toward both water and oily liquids have been developed from various nanocomposites with fluorinated compounds. However, the inherent rigidity and low-surface-energy of these composites restrict their adhesion and practical application in adjusting the surface wettabilities of materials. Here we report a strategy to create hybrid superamphiphobic coating with rapid contact adhesion to various kinds of substrates, strong and controllable adhesive strength, unprecedented capability of mechanical deformations, facile removal, repeatable adhesion, and simple recyclization. Our approach, inspired by snail’s ideal combination of hard shell and soft epiphragm, is versatile and industrially-viable because we use the hydrogel primer to bond the fluorinated nanoparticle finish and substrates. Considering the unique characteristics of these coatings as well as the wide range of available hydrogels and nanomaterials that can be used via this approach, we envision that this snail-inspired strategy will facilitate the development and large-scale production of superamphiphobic coatings.

多功能的蜗牛式超疏水涂层，具有可重复的附着力和可回收性

摘要 各种含氟化合物的纳米复合材料已开发出对水和油性液体具有极端排斥性的超疏水表面。然而，这些复合材料固有的刚性和低表面能限制了它们在调节材料表面润湿性方面的附着力和实际应用。在这里，我们报告了一种创建混合超疏水涂层的策略，该涂层具有对各种基材的快速接触粘附、强大且可控的粘附强度、前所未有的机械变形能力、容易去除、可重复粘附和简单的回收利用。我们的方法受到蜗牛硬壳和软膜的理想组合的启发，用途广泛且在工业上可行，因为我们使用水凝胶底漆来粘合氟化纳米颗粒饰面和基材。
