The poor adhesion of hydrogel antifouling materials on substrates limits their application in marine antifouling. From the perspective of practical application, a lipophilic monomer tackifying strategy is proposed, in which hydrogel coatings can be firmly adhered to substrates very simply. Hydrogel prepolymers containing lipophilic monomers are adhered to the substrate surface after crosslinking, and hydrogel coatings are obtained after drying and absorbing water. The experimental results show that the molar content of lipophilic monomers in the hydrogel reached 42% and can significantly improve its adhesion on the organic substrate. The highly adhesive ability of the hydrogel manifest as its long-term no-shedding ability in the experimental results of static seawater immersion panels, dynamic rotating seawater environments (80 revolutions min−1), and testing-panels in real marine (150 days-no-shedding). A powerful supplement for understanding the direct adhesion of hydrogel coatings to the substrate is provided by this strategy. These hydrogels have a good effect on inhibiting the adhesion of proteins and microalgae and show significant antifouling performance in testing-panels in real marine environments, with great potential for marine antifouling applications.

水凝胶防污涂料通过亲脂性单体具有高附着力
水凝胶防污材料在基材上的附着力差，限制了其在海洋防污中的应用。从实际应用的角度，提出了一种亲油性单体增粘策略，其中水凝胶涂层可以非常简单地牢固地粘附在基材上。含有亲油性单体的水凝胶预聚物交联后附着在基材表面，干燥吸水后得到水凝胶涂层。实验结果表明，水凝胶中亲油性单体的摩尔含量达到42%，可以显着提高其在有机基材上的附着力。在静态海水浸没板、动态旋转海水环境（80 转/分-1 ) 和真实海洋中的测试面板（150 天无脱落）。该策略为了解水凝胶涂层与基材的直接粘附提供了有力的补充。这些水凝胶对抑制蛋白质和微藻的粘附具有良好的抑制作用，在真实海洋环境中的测试面板中显示出显着的防污性能，在海洋防污应用中具有巨大的潜力。
