We report an effective and versatile approach to control marine fouling on artificial surfaces based on specific chemical interactions found in marine mussels. The approach consists of mussel-inspired polydopamine coating, spin-coating-assisted deposition of poly(ethylene glycol) (PEG) catechols, and their cross-linking via catechol-Fe-catechol interactions. Using this approach, multilayered PEG films that were highly resistant to marine diatom adhesion were successfully constructed on various substrates, such as stainless steel, nylon, titanium oxide, and silicon oxide. We believe that our results will provide a basis for the construction of a marine antifouling agent that can be applied by a large variety of industries owing to its applicability to different types of substrates and stability under marine environments.
我们报道了一种基于海洋贻贝中发现的特定化学相互作用来有效控制人工表面海洋附着的通用方法。该方法包括贻贝启发的聚多巴胺涂层、旋涂辅助的聚（乙二醇）（PEG）儿茶酚的沉积，以及通过儿茶酚-Fe-儿茶酚相互作用交联。使用这种方法，我们成功地在各种基底上构建了具有高度抗海洋硅藻附着能力的多层 PEG 薄膜，例如不锈钢、尼龙、氧化钛和氧化硅。我们相信，由于其对不同类型基底的适用性和在海洋环境下的稳定性，我们的结果将为构建一种可应用于多种工业的海洋防污剂提供基础。
