| 中文摘要: |
| 受制于材料本身的性质，有机涂层在服役期间不可避免会遭受物理及化学腐蚀作用而使防护失效。贝壳珍珠层是一种天然的“砖-泥”层状结构的有机-无机复合材料，由于其特殊的层状结构，该材料展现出优异的力学性能和隔绝效果，引起人们对该材料的广泛研究。首先，对“砖-泥”层状结构的增韧机制、材料的仿生制备方法等方面的研究进展进行了回顾。其次，探讨了纳米复合涂层的研究现状，比较了仿生“砖-泥”涂层和传统复合涂层在结构及性能上的差异，结果表明，将“砖-泥”层状结构引入到涂层设计中，将充分发挥片状填料对力学性能和隔绝效果的增强作用，进而在提高涂层对物理和化学腐蚀破坏的抵抗的同时，增强涂层的防护性能。然后，在分析仿生“砖-泥”层状材料现有制备技术优缺点的基础上，探讨了利用电泳沉积技术制备仿生“砖-泥”层状涂层的可行性及其在防腐蚀中的应用前景。最后，介绍了利用电泳沉积构建“砖-泥”层状仿生涂层的研究内容及方案，研究结果将为构建长效防护涂层提供数据支持。 |

| Limited to its peculiar nature, organic coating inevitably suffers from physical and chemical corrosion during service, thus losing protection effect. Shell nacre is a kind of natural organic-inorganic composite material with "brick-and-mortar" layered structure. Because of its special layered structure, the material exhibits excellent mechanical properties and barrier effect, arising extensive research. Firstly, the research progress of the toughening mechanism and preparation methods of "brick-and-mortar" materials was reviewed. Secondly, the research status of nanocomposite coatings was discussed, and the differences of structure and performance between "brick-and-mortar" coatings and traditional composite coatings were compared. The results of discussion showed that the introduction of "brick-and-mortar" layered structure into coating gave full play to the enhancement of mechanical properties and barrier effect of flake fillers, thus improving the resistance of the coating to physical and chemical corrosion damage as well as the protective performance of the coating. Then, the feasibility of preparing "brick-and-mortar" layered coatings by electrophoretic deposition and its application prospect in anti-corrosion coating were discussed by comparing the advantages and disadvantages in the preparation technology of these materials. Finally, the main research contents and proposal of building "brick-and-mortar" layered coatings by electrophoretic deposition were introduced. The research results will present data for the construction of long-term protective coatings. |
