▎ 摘  要

A novel superhydrophilic and underwater superolephobic isotactic polypropylene (iPP) @ polydopamine (PDA) @ graphene oxide (GO) hollow fiber membrane was firstly developed using a facile and eco-friendly process and evaluated for oil-water separation and antifouling properties. The iPP@PDA@GO membrane presented special micro-nano structure and outstanding superhydrophilicity (the water contact angle decreased from 120 degrees to 0 degrees) and underwater superolephobicty (the underwater contact angle increased upto 152 degrees). In addition, the modified membrane exhibited wonderful surfactant-stabilized oil-water emulsions separation performance, including high oil-water permeation (188 L m(-2) h(-1), 0.1 MPa) and superior oil rejection (>99%). indicating that the membrane had excellent antifouling performance and reusability.
