Inspired from fishscales, membranes with special surface wettability have been applied widely for the treatment of oily waste water. Herein, a novel superhydrophilic graphene oxide (GO)@electrospun cellulose nanofiber (CNF) membrane was successfully fabricated. This membrane exhibited a high separation efficiency, excellent antifouling properties, as well as a high flux for the gravity-driven oil/water separation. Moreover, the GO@CNF membrane was capable to effectively separate oil/water mixtures in a broad pH range or with a high concentration of salt, suggesting that this membrane was quite promising for future real-world practice in oil spill cleanup and oily wastewater treatment.
受鱼鳞启发，具有特殊表面润湿性的膜已广泛应用于含油废水的处理。在此，成功制备了一种新型超亲水氧化石墨烯（GO）@静电纺丝纤维素纳米纤维（CNF）膜。该膜表现出高分离效率、优异的抗污染性能和高重力驱动油水分离通量。此外，GO@CNF 膜能够在较宽的 pH 范围或高盐浓度下有效地分离油/水混合物，表明该膜在未来的溢油清理和含油废水处理实际应用中具有广阔的应用前景。
