水凝胶是一种理想的防污材料，因此水凝胶防污涂层材料的设计和应用受到了广泛关注。文章旨在总结水凝胶涂层在海洋防污领域的应用和研究。介绍了海洋污损生物的危害，阐述了水凝胶的防污机制，重点论述了纯水凝胶涂层材料、水凝胶 -有机树脂涂层材料的国内外研究进展。对纯水凝胶涂层材料来说，其设计的重点集中于力学性能的提高、附着力的增强和防污性能的提升；水凝胶 -有机树脂涂层设计研究应注重水凝胶与树脂之间相容性和水凝胶添加量的探索。最后指出水凝胶防污涂层材料存在的问题和发展方向。

Hydrogel is an ideal antifouling material，so the design and application ofhydrogel-based antifouling coating materials have attracted extensive attention. This workaims to summarize the application and research of hydrogel-based coating in the field ofmarine antifouling. Herein，the hazards of marine fouling organisms were introduced，the antifouling mechanism of hydrogels was explained，and the domestic and international research progress of pure hydrogel coating materials and hydrogel-organic resin coating materials wasemphatically reviewed. For pure hydrogel coating materials，the improvement of mechanical properties，adhesion and antifouling performance should be focused on. For hydrogel-organic resin coating，the compatibility issues between hydrogel and resin，and the exploration of hydrogel addition should be paid attention to. Finally，the existing challenges and development directions of hydrogel-based antifouling coating materials were indicated.
