摘要： 与常规的自修复防腐涂层相比，石墨烯基自修复防腐涂层具备较优异的自修复效率及防腐性能，这归因于石墨烯基材料突出的能量转换能力、阻隔效应及物理特性等。文中详细讨论了石墨烯在自修复涂层中的作用以及石墨烯基自修复涂层的研究、应用现状。介绍了本征型和外援型 2种自修复机制；介绍了石墨烯衍生物在本征型自修复材料中主要发挥促进能量转换的作用，在外援型自修复材料中主要作为携带各种修复剂的介质；结合石墨烯衍生物自身特性探究了其对涂料力学性能及阻隔作用的影响；并探究了石墨烯基自修复防腐涂层的实际应用问题以及未来进展方向，指出单一修复机制的涂层仍然存在许多局限性，具有多重修复机制及多功能化的石墨烯基自修复涂层将是未来的发展趋势，实际应用前应结合应用环境开展实地验证。

Abstract: Compared with conventional self-healing anticorrosive coatings，graphene-based self-healing anticorrosive coatings had better self-healing efficiency and anticorrosiveproperties，which was attributed to the excellent energy conversion ability，shielding effect and physical properties of graphene-based materials. In this paper，the function of graphene in self-healing coatings，and the research and application of graphene-based self-healing coatings were discussed in detail. Firstly，two healing mechanisms of self-healing coatings were introduced：intrinsic self-healing mechanism and extrinsic self-healing mechanism. Secondly，the role of graphene derivatives in these two healing mechanisms was introduced. Inintrinsic self-healing materials，graphene derivatives mainly played a role in promoting energy conversion. In extrinsic self-healing materials，graphene derivatives was mainly used as amedium to carry various healing agents. The research progress of graphene-based self-healing coatings was described. Then，the effects of graphene derivatives on the mechanical propertiesand barrier effects of coatings were investigated. Finally，the actual application issues ofgraphene-based self-healing anticorrosive coatings and future development directions havebeen explored. It was investigated that there are still many limitations of coatings with singlehealing mechanism，and graphene-based self-healing coatings with multiple healingmechanisms and multifunctionality would be the new trend of development in the future，which should be verified in the field in combination with application environments before actualapplication.
