NOVELTY - Preparation of hydrophobic membrane comprises drying graphene oxide (GO) and zinc oxide (ZnO) nanowires at 323 K for 12 hours; dissolving 20 g GO powder in 50 mL deionized water, and ultrasonically treating for 30 minutes to form uniform GO dispersion; adding 5-20 wt.% ZnO nanowires to GO dispersion and ultrasonicating for 30 minutes to completely disperse nanowires and form uniform mixing system; with PVDF microfiltration membrane as base layer, suction filtering GO/ZnO nanowire mixture on membrane surface using vacuum filtration device; and vacuum drying at 313 K for 24 hours. USE - The method is used for preparing hydrophobic membrane for oil-water separation. ADVANTAGE - The film shows good permeability and high efficiency in oil-water separation performance.
