Corrosion and biofouling are two main deterioration effects for shortening the service life of metal material in marine environment. In this study, targeting corrosion and biofouling of Cu, a bioinspired liquid-infused surface (LIS) coating based on metal organic frameworks (MOFs) is constructed onto Cu by sequential steps, including oxidation, coordination reaction, thiol modification and infusion process. The microstructure, chemical composition and wettability of the coating are uncovered through different characterization techniques, such as scanning electron microscopy, high-resolution transmission electron microscopy, electron diffraction, X-ray photoelectron spectroscopy and so forth. Corrosion durability test results show that MOF-LIS performs high corrosion inhibition to underneath Cu. As a representative guiding parameter, R_ct of MOF-LIS reaches 5.26 × 10⁷ Ω cm², which is much higher than that of bare Cu (694.6 Ω cm²), illustrating a corrosion inhibition efficiency up to 99.999% for Cu metal. Using diatoms as the probe organisms, after being immersed in seawater for 8 d, the attaching diatoms density on MOF-LIS (7.33 × 10⁴ cells/cm²) is much less than bare Cu surface (3.95 × 10⁸ cells/cm²), illustrating the high biofouling inhibition efficiency. Therefore, the versatile properties enable MOF-LIS as a coating having potential usage for anti-corrosion and anti-biofouling in the marine environment.

腐蚀和生物污染是缩短金属材料在海洋环境中使用寿命的两个主要劣化效应。在这项研究中，针对铜的腐蚀和生物污染，通过氧化、配位反应、硫醇改性和灌注工艺等步骤，在铜上构建了一种基于金属有机骨架 (MOF) 的仿生液体灌注表面 (LIS) 涂层。通过不同的表征技术，如扫描电子显微镜、高分辨率透射电子显微镜、电子衍射、X射线光电子能谱等，揭示了涂层的微观结构、化学成分和润湿性。耐腐蚀试验结果表明，MOF-LIS 性能高对Cu下面的腐蚀抑制。作为具有代表性的指导参数， MOF-LIS 的R _ct达到 5.26 × 10 ⁷ Ω cm ²，远高于裸铜的 R ct （694.6 Ω cm ²），说明铜金属的缓蚀效率高达 99.999%。以硅藻为探针生物，在海水中浸泡8 d后，MOF-LIS上的附着硅藻密度（7.33×10 ^{4 个}细胞/cm ²）远低于裸铜表面（3.95×10 ⁸个细胞/cm ^{2 ）})，说明了高生物污垢抑制效率。因此，多功能特性使 MOF-LIS 作为一种涂层在海洋环境中具有防腐蚀和防生物污染的潜在用途。
