外文摘要：With the rapid development of the aviation industry, research on aircraft engine fuel filtration has gained increasing attention. However, conventional filtration materials often suffer from limited functionality, poor durability under extreme conditions, and inability to handle complex pollutants such as microplastics and soluble organics. To address these challenges, a new superhydrophobic filter membrane (NSF) inspired by the lotus leaf was fabricated via spraying technology using MnO2, 1 H, 1 H, 2 H, 2H-perfluoroalkyltriethoxysilanes (POTS), and g-C3N4@Zn-Ti-LDH. It exhibits a water contact angle of 158 +/- 2 degrees and a sliding angle of 7 degrees. The NSF not only separates various impurities from high-viscosity oil under photothermal conditions but also demonstrates remarkable microplastic adsorption (up to 0.50 g & sdot;L-1 for PP/PE/PVC) and photocatalytic degradation of organic pollutants such as methylene blue. Its performance stems from a hierarchical micro/nanostructure that traps air and repels water, combined with the photocatalytic activity of g-C3N4@Zn-Ti-LDH. Notably, the filter maintains a separation efficiency of over 96 % even after multiple cycles. Its performance and exceptional stability have been validated through COMSOL simulations of the oil-water interface, which provide detailed insights into the separation process. This durable bionic filter offers integrated multifunctionality-enabling efficient oil purification, high-capacity microplastic capture, and self-cleaning-effectively reducing maintenance needs and extending service life under extreme conditions.
