Membranes with special wettability (superhydrophobic/superoleophilic or superhydrophilic/superoleophobic) had been introduced to separate oil/water emulsions. Nevertheless, the surface or pore canals of membrane easily fouled by oily wastewater are the tough challenges towards longtime application. In this work, a PVDF@PDA@ZnO membrane was firstly fabricated via growth of ZnO nanoparticles from ZnO seeds planted on the PVDF@PDA membrane. This PVDF@PDA@ZnO membrane showed good separation capability for various emulsions (which the separation efficiencies and fluxes were up to 99.1% and 654 L m(-2) h(-1) , respectively). The degradation rate of MB solution treated by the composite membrane was almost 100% attributing to the excellent photocatalytic ability of ZnO. Moreover, the composite membrane could maintain high efficiency (above 99.27%) after long-time emulsions separation/UV-light irradiation, which displayed superior UV-driven self-cleaning and oxidation resistance performance. This self-cleanable composite membrane possessed durability and held high promise for long-time oil/water emulsions separation. (C) 2020 Taiwan Institute of Chemical Engineers.
