To address the poor oil–water separation efficiency and bactericidal properties of existing oil–water separation membranes for the treatment of industrial oily wastewater discharge, this study designed an in-and-out coating material for modifying the inner site and outer surface of porous activated carbon fabric (ACF) using urethane reactions. To this end, fluorinated polyurethane (F-PU) coating materials were synthesized using perfluoroalkyl alcohol, ethylene glycol (EG), and isophorone diisocyanate (IPDI). Subsequently, the inner and outer surface of the ACF were coated with F-PU via the urethane reaction of the hydroxyl groups (–OH) of the surface of ACF and the isocyanates of F-PU. The successfully fabricated in-and-out F-PU-coated heterogeneous fabric exhibited excellent hydrophobic properties, anti-scratch performance, oil–water separation performance, and bacterial penetration blocking efficiency (>99% for gram negative and gram positive bacteria). Furthermore, the in-and-out-coated ACF exhibited high durability, and retained its bacterial penetration blocking performance after scratch tests.

针对现有油水分离膜处理工业含油废水的油水分离效率和杀菌性能差的问题，本研究设计了一种内外涂层材料，用于改性多孔活性物质的内表面和外表面。使用聚氨酯反应的碳纤维织物 (ACF)。为此，使用全氟烷基醇、乙二醇 (EG) 和异佛尔酮二异氰酸酯 (IPDI) 合成了氟化聚氨酯 (F-PU) 涂层材料。随后，通过 ACF 表面的羟基 (-OH) 与 F-PU 的异氰酸酯的氨基甲酸酯反应，在 ACF 的内外表面涂上 F-PU。成功制备的内外 F-PU 涂层异质织物表现出优异的疏水性能、抗划伤性能、油水分离性能和细菌渗透阻断效率（革兰氏阴性和革兰氏阳性细菌 > 99%）。此外，内外涂层的 ACF 表现出高耐久性，并在划痕测试后保持其细菌渗透阻挡性能。
