| 有机涂层固有缺陷以及在外界破坏下会导致涂层防护失效，传统填料和单一的缓蚀剂在改善涂层防腐性能上仍面临着挑战。近年来，金属有机框架材料(MOFs)凭借其稳定、与涂层相容性较好、智能释放等特性，成为了增强有机涂层防腐性能的新型材料。概述了MOFs增强有机涂层防腐性能的优势，着重从MOFs提升涂层被动防腐性、提供自愈合的主动防腐性两方面阐述其作用机制以及研究现状，简单归纳了MOFs经过分子修饰和复合其他材料在增强涂层防腐性能上所起到的作用和实现的协同防腐机制，同时在主动防腐中归纳了MOFs构建智能涂层的缓蚀剂负载策略和各自存在的问题。在增强涂层被动防腐性上MOFs可提升涂层的交联密度并填充涂层固有缺陷，以降低涂层孔隙率，其中MOFs经修饰后可进一步强化涂层的防腐性能;在主动防腐方面，MOFs通过负载缓蚀剂可在涂层中实现缓蚀剂的智能释放，赋予涂层自愈合性能，同时MOFs与其他材料复合后可实现主被动一体的协同防腐。最后，对未来利用MOFs增强有机涂层防腐性能的发展方向进行了展望，以此希望为MOFs在提升有机涂层防腐性能中的运用提供一定的参考。 |

| Organic coatings are commonly acknowledged within the realm of metal corrosion protection for their superior adhesion to metals, exceptional barrier properties, electrical insulation capabilities, and cost-effectiveness. However, the failure of organic coating protection can be ascribed to both internal defects and external damage. Traditional fillers and single corrosion inhibitors still face challenges in enhancing the corrosion protection of coatings. In recent years, metal-organic frameworks (MOFs) have become a new type of material to enhance the corrosion resistance of organic coatings by virtue of their stability, good compatibility with coatings, and smart release. This paper reviews the benefits of incorporating MOFs in enhancing the corrosion resistance of organic coatings, focusing on the mechanism of MOFs and the current research status in terms of enhancing the passive corrosion resistance of coatings and providing self-healing and active corrosion resistance. In these two aspects, the key role played by MOFs is briefly summarized in enhancing the corrosion resistance of coatings through molecular modification and compounding of other materials. Furthermore, the synergistic anti-corrosion mechanism of MOFs with other molecular compounds is discussed. Additionally, selection and loading strategies of MOFs on corrosion inhibitors in smart anti-corrosion coatings are summarized, along with the associated challenges. In terms of enhancing the passive corrosion resistance of coatings, the active sites contained in the MOFs in coatings participate in the cross-linking curing reaction of coatings in the form of Lewis acids and Lewis bases, and the pore configurations within the MOFs provide a suitable contact space for the curing reaction of the coating molecules, which increases the cross-linking density of coatings. In addition, certain MOFs act as a stable filler to fill the pores of coatings to address the inherent defects of coatings. It is used to reduce the porosity of coatings, and finally improve the barrier property of coatings to corrosive ions. In terms of strengthening the active anti-corrosion performance of coatings, the utilization of MOFs to stimulate response characteristics and load corrosion inhibitors in a targeted corrosion environment enables structural modifications and controlled release of inhibitors, so as to achieve the purpose of intelligent release of corrosion inhibitors, and promote the self-repair of damaged coatings. MOFs intelligent coating corrosion inhibitors can be derived within the MOFs themselves and the loading of exogenous corrosion inhibitors. Here, the protection mechanism of different types of corrosion inhibitors for metals is summarized. And some MOFs materials with corrosion inhibition properties, their corrosion inhibition components and response mechanisms are listed. Moreover, the loading methods of exogenous corrosion inhibitors are reviewed, including in-situ loading and loading of corrosion inhibitors after the synthesis of MOFs. Also, the advantages and shortcomings of the loading strategies of various corrosion inhibitors are explored. Finally, the potentials and shortcomings of MOFs in improving the corrosion resistance of organic coatings are discussed, and certain insights are provided for MOFs in improving the corrosion resistance of organic coatings in terms of environmental protection, anti-corrosion mechanism, and predicted corrosion resistance, in the hope of providing certain reference values for the use of MOFs in enhancing the corrosion resistance of organic coatings. |
