Anti-fouling copper hydroxide nanowires (CHNs)-graphene oxide (GO) nanocomposites membrane was fabricated by a vacuum-assisted filtration self-assembly process. CHNs were covered on the surface and inserted into the interlayers of the GO nanosheets to form the rough surface and nanostructure channels. The membrane with water contact angles (CAs) of 53° and oil CAs of 155° exhibited superior stability, hydrophilicity, underwater superoleophobicity and ultralow oil adhesion, and hence it could separate the oil-water emulsion with a high efficiency of >99%. This membrane showed the combined advantages of high oil rejection rate and ultralow membrane fouling, making it promising for practical oil-water emulsion separation applications.
通过真空辅助过滤自组装工艺制备了防污氢氧化铜纳米线（CHNs）-氧化石墨烯（GO）纳米复合膜。CHNs覆盖在GO纳米片的表面并插入其层间，形成粗糙表面和纳米结构通道。该膜的水接触角（CAs）为53°，油接触角为155°，具有优异的稳定性、亲水性、水下超疏油性和超低油粘附性，因此能够以>99%的高效率分离油水乳液。该膜具有高拒油率和超低膜污染的综合优势，在实际油水乳液分离应用中具有广阔前景。
