Superhydrophobic surfaces show wide prospects in a variety of applications requiring self-cleaning, anti-fog, anti-ice, anti-corrosion and anti-fouling properties, which have attracted the attention of many researchers. However, superhydrophobic surfaces are inevitably affected by chemical corrosion, scratches and wear in practical applications, resulting in the loss of superhydrophobicity. To solve this problem, researchers have developed superhydrophobic surfaces with self-healing properties. In this paper, the research achievements of self-healing superhydrophobic materials in recent years are summarized, and the preparation and repair principle of self-healing superhydrophobic surfaces are introduced from three aspects: surface chemical composition repair, surface roughness repair and double repair. In addition, some multifunctional self-healing superhydrophobic surfaces are introduced, such as conductive, stretchable, antibacterial, . Finally, in order to provide a reference for the preparation of widely used long-acting superhydrophobic materials, some existing problems and future development prospects are described in order to attract more researchers' attention and promote the development of this field.
超疏水表面在需要自清洁、防雾、防冰、防腐和防污等性能的各种应用中具有广阔的前景，引起了许多研究人员的关注。然而，超疏水表面在实际应用中不可避免地会受到化学腐蚀、划伤和磨损的影响，导致超疏水性的丧失。为了解决这个问题，研究人员已经开发出具有自修复性能的超疏水表面。本文总结了近年来自修复超疏水材料的研究成果，从表面化学成分修复、表面粗糙度修复和双重修复三个方面介绍了自修复超疏水表面的制备和修复原理。此外，还介绍了一些多功能的自修复超疏水表面，如导电、可拉伸、抗菌等。最后，为了为制备广泛使用的长效超疏水材料提供参考，描述了一些现有的问题和未来的发展前景，以吸引更多研究人员的关注，推动该领域的发展。
