Abstract Developing highly durable coatings, endowing comprehensive protection capabilities of antifouling, drag reduction, and corrosion resistance in underwater settings, holds paramount significance for modern maritime undertakings. However, the inferior multifunctional compatibility weak structural strength have proven to pose an extremely formidable challenge. Herein, this study reports internally self‐sliding coating that imparts liquid‐repellence ion permeation without necessity a complex fabrication process. The key lies combining integrated structure‐function strategy with particle close‐packing method fluorine‐grafted layered silicate particles. These particles demonstrate exhibit unique property due van der Waals forces between lamellae from typical crystal structure. durability these coatings are clearly demonstrated by their outstanding mechanical wear resistance, reduction efficiency up 25%, capacity remain corrosion‐free saltwater over 1000 h. Owing slippery frictional action closely packed surface microstructure, demonstrates long‐term stability anti‐permeability properties. This offers universal design framework engineering ultra‐durable applicable diverse range applications.

Marine biofouling causes significant economic losses, and conventional antifouling methods are often associated with environmental pollution. Hydrogen peroxide (H2O2), as a clean energy source, has gained increasing attention in recent years. Meanwhile, electrocatalytic 2e− oxygen reduction reaction (ORR) for H2O2 production received growing interest. However, the majority of current studies conducted on acidic or alkaline electrolytes, research ORR neutral NaCl solutions remains rare. Here, bimetallic Zn-Cd zeolitic imidazolate framework (ZnCd-ZIF) is rationally designed to achieve chloride-resistant catalysis under simulated seawater conditions (pH 7.5, 3.5% Cl−). Experimental results demonstrate that ZnCd-ZIF catalyst exhibits an exceptional selectivity 70% at 0.3 VRHE, surpassing monometallic Zn-ZIF (60%) Cd-ZIF (50%). Notably, reaches 120 mmol g−1 Cl−-containing electrolyte, exhibiting strong resistance structural corrosion Cl− poisoning. This work not only pioneers effective strategy designing catalysts adapted marine environments but also advances practical implementation seawater-based electrochemical synthesis.
