Abstract: ZIF-8/ZnO layer was prepared on the surface of AA7075 aluminum alloy via electrochemical deposition and hydrothermal process, 1H,1H,2H,2H-perfluorodecyl-triethoxysilane (PFDS) was then applied to form a superhydrophobic conversion membrane (PFDS/ZIF-8/ZnO). The microstructure, chemical properties, hydrophobicity, and corrosion resistance of PFDS/ZIF-8/ZnO were analyzed by scanning electron microscopy (FESEM), Fourier transforms infrared spectroscopy (FTIR), contact angle measurement, and electrochemical impedance spectroscopy (EIS), respectively. The results showed that contact angle of PFDS/ZIF-8/ZnO reached 156°, benefiting from micro/nanostructures and low-surface energy modification. After immersing in 3. 5% NaCl solution for 9 days, |Z|_{0. 01 Hz} (the low-frequency impedance at 0. 01 Hz) still exceeded 10⁶ Ω ·cm², which showed high corrosion resistance and durability. The antibacterial test results showed that the antibacterial rate of the film layer could reach 80. 6%, demonstrating good antibacterial ability.
