超滑涂层在防污领域的应用受到广泛关注，但其表面润滑的可控性相对不足且涂层在服役过程中容易产生裂纹造成被动失效。通过引入偶氮苯基团与环糊精分子制备了一种具有光热响应特性的自修复超滑涂层，其通过光照作用释放硅油来调节表面润滑性，实现抗菌功能。此外，偶氮苯的光热异构转化能使涂层的表面温度在 300 s内升高至 70 ℃，基于二硫键和氢键的自修复涂层，其自修复效率可达到 94. 7%。活死菌实验也证实了光热作用下涂层表面优异的抗菌性能，该涂层具有高效的自修复抗菌性能，在海洋装备和其他防污领域具有广阔的应用前景。

Superslippery coating has been widely concerned in the field of anti-pollution，but its surface lubrication is relatively insufficient and the coating is prone to crack during service，resulting in passive failure. In this study，a self-healing superslippery coating with photothermal response was prepared by introducing azophenyl groups and cyclodextrin molecules. The surface lubricity of the coating was adjusted by releasing silicone oil under the action of light to achieve antibacterial properties. In addition，the photothermal isomerization of azobenzene could increase the surface temperature of the coating to 70 ℃ during 300 s，and the repair efficiency of the coating can reach 94. 7% by introducing the interaction of disulfide bond and hydrogen bond. The live and dead bacteria experiments also confirmed the excellent antibacterial properties of the coating surface under the action of light and heat. In summary，the coating indicated efficient self-healing antibacterial properties，and has broad application prospects in marine equipment and other anti-pollution fields.
