| 英文摘要 | The development of mechanically stable superhydrophobic materials with durable corrosion resistance remains a significant challenge in materials science. In this paper, inspired by rubber running tracks, we designed a triple-layered armored superhydrophobic composite coating comprising epoxy resin (EP), recycled tire rubber particles (RTR Ps), fluorosilane-modified aluminum oxide (Al2O3) nanoparticles, and thermoplastic polyurethane elastomers (TPU) spray-coated on Q235 carbon steel. A comprehensive investigation was performed to systematically evaluate the surface wettability, morphological characteristics, chemical composition, self-cleaning capability, mechanical stability, and corrosion resistance properties. The resulting RTR armored super-hydrophobic composite coating exhibits exceptional mechanical robustness, withstanding 1200 sandpaper abrasion cycles, 450 tape-peeling cycles, and 1050 g sand impact. Electrochemical measurements reveal seven orders of magnitude increase in low-frequency impedance modulus (|Z|0.01Hz) and charge transfer resistance (Rct) relative to bare Q235 carbon steel, along with five orders of magnitude decrease in corrosion current density (Icorr). Additionally, long-term corrosion resistant testing demonstrated retention of superhydrophobicity after 840 h of 3.5 wt% NaCl immersion and 1680 h of outdoor marine atmospheric exposure. This RTR armored design establishes a new paradigm for sustainable, ultra-durable protective coatings with potential applications in marine infrastructure, transportation, and energy systems. |
