| 在过去的二十年中，超疏水涂层在不同领域中的应用取得了巨大进步，但仍然存在机械稳定性差、容易受到外界影响导致超疏水性丧失等问题，阻碍了超疏水涂层的实际应用。因此，为了延长超疏水涂层的使用寿命，赋予其自修复特性具有重要的实践和应用意义。从超疏水涂层的理论基础和应用实践的角度出发，简要介绍了超疏水涂层的背景和关键概念。详细介绍了常见的自修复超疏水涂层的自修复机制，根据修复原理的不同，分为外源性自修复和本征自修复。根据超疏水涂层的不同失效形式，包括低表面能丧失、涂层结构破坏及低表面能和涂层结构同时被破坏的情况，讨论了针对不同失效形式的自修复超疏水涂层的修复策略。从实际应用的角度出发，重点讨论了生态环保、可持续发展和自主响应的自修复超疏水涂层设计策略。总结了自修复超疏水涂层在防冰除冰、油水分离和防腐蚀方面的应用，着重总结了关键的实验研究和主要发现，并详细描述了自修复超疏水材料和自修复机制等。最后简要总结了当前自修复超疏水涂层所面临的挑战和未来的研究方向。 |

| Superhydrophobic surfaces refer to special surfaces with a water contact angle of greater than 150° and a roll-off angle of less than 10°. They are ubiquitous in nature, such as lotus leaves, dragonfly wings, sagebrush leaves, shark skin, and water strider legs. In recent years, superhydrophobic surfaces have attracted extensive attention due to their application in anti-icing, anti-corrosion, self-cleaning, oil-water separation, and drag reduction. With the increasing development demands and the progress of in-depth research, superhydrophobic coatings have become a hot research topic in scientific exploration. Based on the functional design of superhydrophobic coatings, researchers are committed to developing environmentally friendly, durable, and repairable superhydrophobic coatings, while expanding their advanced application fields. Over the past two decades, superhydrophobic coatings have made significant progress in various fields, but these surfaces still have poor mechanical stability, making them vulnerable to the influence of the external environment and resulting in the loss of superhydrophobic properties, which hinders their long-term use and practical application. In order to extend the service life of superhydrophobic coatings, on the one hand, the micro-nano structure stability and the self-healing property of the coating surface are given. Therefore, developing self-healing superhydrophobic coatings is currently a hot research direction. However, due to the health hazards of fluorides, the unsustainability of petroleum-based materials, and the difficulty of autonomous response, the current self-healing superhydrophobic coatings still cannot be widely applied. Firstly, based on the theory and application of superhydrophobic coatings, the repair mechanism of self-healing superhydrophobic coatings is introduced. The self-healing mechanisms are divided into exogenous self-healing and intrinsic self-healing. According to the different loading methods of the healing agents, common exogenous self-healing can be further classified into microcapsule loading and porous material loading. Intrinsic self-healing can be divided into reversible covalent bond and reversible non-covalent bond self-healing. The ways to repair coatings based on reversible covalent bond interactions include Diels-Alder reactions, disulfide bonds, and imine bonds, etc. The self-healing of superhydrophobic coatings based on non-covalent bonds is mainly achieved through hydrogen bonds and metal coordination, etc. According to the principle of superhydrophobicity, the failure forms of superhydrophobic coatings are classified into three categories:the loss of superhydrophobicity due to the increase in surface energy of the coating, the inability to maintain superhydrophobicity due to the destruction of the coating structure, and the simultaneous occurrence of structural damage and increase in surface energy in superhydrophobic coatings. For different failure forms, different countermeasures are summarized to restore low surface energy and microstructure. In addition, due to the increasingly serious ecological and environmental problems, the design strategies of self-healing superhydrophobic coatings with practical application values are reviewed in detail, including non-fluorinated design of coating materials, design of bio-based superhydrophobic materials, and self-healing superhydrophobic coatings with self-response. Finally, the applications of self-healing superhydrophobic coatings in anti-icing, oil-water separation, and anti-corrosion are summarized. The key experimental research and main findings of self-healing superhydrophobic materials are reviewed, and the self-healing superhydrophobic materials, coating preparation methods, and self-healing mechanisms are introduced in detail. Finally, the challenges and future research directions of self-healing superhydrophobic coatings are pointed out. |
