英文摘要The construction of superhydrophobic materials as an effective anti-corrosion method has become a scientific consensus. However, two major challenges still hinder their transition from laboratory development to practical applications: insufficient interfacial mechanical stability and the inability of laboratory evaluation methods to accurately predict protective behavior and adaptability in real service environments. In this study, we designed a silica sand (SiO2) armored superhydrophobic composite coating, primarily composed of three layers: epoxy resin (EP) layer, large-scale SiO2 layer, and superhydrophobic 1H, 1H, 2H, 2H-perfluorodecyltriethoxysilane-modified titanium dioxide (F-TiO2) @ EP layer. Field-emission scanning electron microscope (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), contact/sliding angle measurements, sandpaper abrasion tests, electrochemical analysis, and neutral salt spray tests were used to evaluate the surface morphology, chemical composition, wettability, interfacial stability, and laboratory anti-corrosion performance. The results showed that the coating maintained a water contact angle (WCA) of 150.4 f 0.4 degrees and a sliding angle (SA) of 9.4 f 0.2 degrees even after 2000 sandpaper abrasion cycles (400 m abrasion distance), demonstrating exceptional mechanical stability. The low-frequency impedance modulus (|Z|0.01Hz) and charge transfer resistance (Rct) of the coating increased by five orders of magnitude, and the coating withstood 720 h of salt spray testing, confirming its superior anti-corrosion performance at the laboratory stage. More importantly, we evaluated the anti-corrosion performance of the prepared superhydrophobic coating in four corrosion zones of a real marine corrosion environment. The results revealed that the coating exhibited sustained anti-corrosion properties in the marine atmospheric zone and the splash zone. However, its long-term durability in the tidal zone and submerged zone was limited, indicating the need for further improvement and reinforcement.
