| 英文摘要 | Superhydrophobic materials hold great promise as anti-corrosion and anti-icing coatings, yet their practical application is often limited by the use of fluorinated compounds and insufficient mechanical durability. Designing environmentally friendly and highly stable superhydrophobic protective materials remains a key challenge in the field. Herein, we report a fluorine-free, mechanically robust superhydrophobic coating using white corundum (WC) as the skeleton structure, exhibiting a water contact angle (CA) of 151.5 f 1.3 degrees and a sliding angle (SA) of 5.0 f 0.7 degrees. The coating comprises three distinct layers: bottom epoxy resin (EP) layer, intermediate WC layer, and superhydrophobic top layer. Given in the multi-scale WC armored design, the coating demonstrates significantly enhanced mechanical stability, withstanding 2000 sandpaper abrasion cycles and 2400 tape-peeling cycles. Moreover, the coating exhibits superior anti-corrosion and anti-icing performance. The charge transfer resistance (Rct) and low-frequency impedance modulus (|Z|0.01Hz) increased by six orders of magnitude compared to bare aluminum alloy. At-10 degrees C and-15 degrees C, the freezing time of water droplets on the coated surface was prolonged by 14.4 and 12.7 times, respectively. We believe this design of a fluorine-free, ecofriendly, and highly stable superhydrophobic coating offers significant advantages for real-world applications. |
