摘要

•Quaternary ammonium and zwitterion dual-functionalized PDB-b-PSB brushes on MF membrane surface were fabricated.•The membrane pore size was not significantly changed by the coating.•Surface hydrophilicity of M/PDB-b-PSB membrane enhanced obviously.•M/PDB-b-PSB membrane with passive anti-adhesive and upper active biocidal properties.•Modification strategy for ant-biofouling membrane was facile and promising.
