摘要

金属涂层的完整性和耐久性对钢结构的耐介质腐蚀影响很大。微纳米胶囊型填料能在防腐涂层发生局部破损或者出现微裂纹时，对涂层下微环境变化产生应激响应，释放出缓蚀性物质或者聚合物单体，实现对涂层的自修复，填充空隙，从而显著提高涂层的抗介质腐蚀能力。首先介绍了微纳米自修复涂层的原理，并以介孔SiO2、层状双氢氧化物、埃洛石纳米管和金属有机框架化合物等几种新型微纳米填料为代表，对其在自修复高耐蚀涂层上的应用和优缺点进行了简单的总结和展望，为高耐蚀长效涂层的开发提供一些思路。

Abstract

The integrity and durability of metal coatings have a great influence on the medium corrosion resistance of steel structures. When the anti-corrosive coating was partially damaged or microcracked, the micro-nano capsule filler could produce a stress response to the changes in the micro-environment under the coating, release corrosion-inhibiting substances or polymer monomers, and realize the self-healing of the coating, filling the voids, and thereby significantly improving the medium corrosion resistance of coating. In this work, the principle of micro-nano self-healing coating was introduced firstly. Taking several new micro-nano fillers such as mesoporous SiO2, layered double hydroxide, halloysite nanotubes and metal organic framework compounds as representatives, their application, advantages and disadvantages in self-healing high corrosion resistant coatings were summarized and forecasted briefly, which could provide several ideas for the development of high corrosion resistant and long-lasting coatings.

Key words： self-healing coating; mesoporous SiO₂; layered double hydroxide; halloysite nanotubes; metal organic framework compounds
