Superhydrophobic rubber composites have broad application prospects in national defense, industrial and agricultural production and daily life due to their special surface wettability. However, its poor durability at present seriously limits its practical application. Microstructure and low surface energy substances are the decisive factors to realize superhydrophobic surface. Therefore, three strategies to improve the durability of superhydrophobic surface were put forward, including improving the mechanical strength of microstructure, enhancing the adhesion between coating and substrate, and constructing self-repairing surface. On this basis, the preparation techniques of durable superhydrophobic rubber composites were summarized, and then the evaluation methods of durability of superhydrophobic rubber composites were introduced in detail from mechanical durability and chemical durability.
超疏水橡胶复合材料由于其特殊的表面润湿性，在国防、工农业生产和日常生活中有广泛的应用前景。然而，其目前较差的耐久性严重限制了其实际应用。微观结构和低表面能物质是实现超疏水表面的决定性因素。因此，提出了提高超疏水表面耐久性的三种策略，包括提高微观结构的机械强度、增强涂层与基底之间的附着力和构建自修复表面。在此基础上，总结了耐久性超疏水橡胶复合材料的制备技术，并从机械耐久性和化学耐久性两个方面详细介绍了超疏水橡胶复合材料耐久性的评价方法。
