| 英文摘要 | The fabrication of superhydrophobic functional materials relies on the use of fluorine-containing chemical reagents, which not only pose threats to the ecological environment and human health but also significantly limit the sustainable development of materials. In this paper, we designed a fluorine-free superhydrophobic coating on 5083 aluminum (Al) alloy substrates using aluminum oxide (Al2O3) nanoparticles, stearic acid (STA), and polydimethylsiloxane (PDMS) to achieve anti-corrosion and anti-icing properties. Surface wettability, morphology, and chemical composition analyses confirmed that the coating possesses micro-nano hierarchical structures and low surface energy. Water droplet freezing tests at-10 degrees C and-15 degrees C revealed that the ice formation time of the coating was 4.69 times and 1.48 times longer than that of bare 5083 Al alloy, respectively. Electrochemical impedance spectroscopy (EIS) results demonstrated that the charge transfer resistance (Rct) and low-frequency impedance modulus (|Z|0.01 Hz) of the coating increased by five orders of magnitude, indicating outstanding anti-corrosion performance. Additionally, the designed fluorine-free superhydrophobic coating maintained its superhydrophobicity after 35 sandpaper abrasion cycles and 45 tape-peeling cycles, and could be applied to diverse substrates such as copper, wood, glass, and paper, demonstrating good mechanical stability and substrate applicability. |
