摘要

金属腐蚀是工业领域面临的严峻问题，传统防腐涂层因易受环境侵蚀和机械应力产生裂纹，导致防护性能下降和修复困难。自修复防腐涂层因具备智能修复特性——无需频繁人工干预即可自主恢复防腐功能，现已成为防腐领域的研究热点之一。本文对自修复防腐涂层进行了系统性的综述，重点分析了外援型与本征型这2大体系的分类、修复机制、制备方法及性能特点。外援型涂层借助微胶囊或纳米容器负载修复剂或缓蚀剂，涂层损伤时释放修复剂填补裂纹或缓蚀剂与基体反应形成保护膜，提升防腐性能，实现自修复。本征型涂层无需外部添加，依赖涂层自身的动态化学键以及形状记忆效应，即可通过键的可逆重组来实现损伤修复。

Abstract

Metal corrosion is a serious problem in the industrial field

and traditional anti-corrosion coatings are prone to cracking during service owing to mechanical stress or environmental erosion

leading to a decline in protective performance and difficulties in repair. Self-healing anti-corrosion coatings have become a key research focus in the field of corrosion protection owing to their intelligent repair characteristics

which autonomously restore anti-corrosion functions without frequent manual intervention. This paper systematically reviews the research progress of self-healing anti-corrosion coatings

focusing on the analysis of the repair mechanism

preparation methods

and performance characteristics of the two major systems

namely

externally assisted and intrinsically assisted coatings. With the help of microcapsules or nanocontainers loaded with restorative agents or corrosion inhibitors

when the coating is damaged

the restorative agents are released to fill the cracks

or the corrosion inhibitors react with the substrate to form a protective film

which improves the anticorrosion performance and realizes self-healing. Intrinsic coatings rely on the dynamic chemical bonding and shape memory effect of the coating itself and can repair damage through the reversible reorganization of these chemical bonds or molecular chain movement without external additives.
