Mussel-inspired polydopamine (PDA) coatings have been broadly exploited for constructing functional membrane surfaces. One-step codeposition of PDA with antifouling polymers, especially zwitterionic has regarded as a promising strategy fabricating However, one challenge is that the usually slow process over 10 h or even several days. Herein, we report CuSO4/H2O2 able to notably accelerate poly(sulfobetaine methacrylate) (PSBMA). In our case, PSBMA facilely anchored polypropylene microporous (PPMM) surfaces within 1 assistance because its strong interfacial adhesion. The PDA/PSBMA-coated PPMMs show excellent surface hydrophilicity, high water permeation flux (7506 ± 528 L/m2·h at 0.1 MPa), and an outstanding property. Moreover, property maintained after membranes are treated acid alkali solutions well organic solvents. To recap, it provides facile, universal, time-saving exploiting high-efficiency durable
