| 摘要: |
| 超疏水涂层在自清洁、防腐蚀、抗凝冰、减阻等领域具有广阔的应用前景，但其耐久性还有待提高。由于微胶囊在修复剂的封装、制备等方面具备独特优势，利用微胶囊技术将修复剂封装，均匀分散于超疏水涂层后，涂层可同时具有疏水性和自修复性，但目前对微胶囊技术与超疏水涂层结合并进行归纳总结的文献较少。总结了微胶囊技术在超疏水材料自修复领域的研究现状，归纳了微胶囊超疏水涂层自修复的修复机理与常用制备方法，对不同刺激响应方式下微胶囊超疏水涂层的性能(响应速度、自修复效果、耐久性、耐磨性)进行对比。结果表明，以紫外光照射为修复手段的涂层机械耐久性较好，近红光刺激响应是微胶囊超疏水自修复涂层中响应修复效率最快、修复效果最好的修复方式，并且以紫外光和近红光双重刺激响应的超疏水涂层的耐久性、耐化学腐蚀性远超过单一刺激响应型超疏水自修复涂层。最后，提出当前基于微胶囊技术的超疏水自修复涂层存在的问题并对该涂层的应用前景进行展望。 |

| Abstract: |
| Superhydrophobic coating can be used in diverse areas such as self-cleaning, anti-corrosive, anti-icing, drag reduction and so on, but the durability of superhydrophobic coating needs to be improved. Microcapsules have unique advantages in encapsulation and preparation of repair agents. Microcapsules are used to encapsulate the repair remediation agent into the superhydrophobic coating, which has superhydrophobic and self-healing properties. However, few researchers have summarized the combination of microcapsules and superhydrophobic coating. The research status of superhydrophobic coatings is summarized. Meanwhile, the healing mechanism and the preparation methods of superhydrophobic coating are provided. The performance of the prepared superhydrophobic coating with self-healing characteristic responded to different patterns is compared. The comparison includes response speed, self-healing, durability, and abrasion resistance. By comparison, it turns out that the self-healing of superhydrophobic coatings excited by ultraviolet (UV) irradiation possesses the best mechanical endurance. And the durability and chemical corrosion resistance of the superhydrophobic coatings simulated by UV and near red light are much better than those superhydrophobic coatings simulated by a single factor. Finally, the existing problems of superhydrophobic and self-healing coating based on microcapsule are proposed and the application prospect are prospected. |
