摘要

•A facile and green surface modification protocol is developed.•UiO-66-NH2 enlarges the membrane porosity and water flux.•Reaction with amino groups in UiO-66-NH2 realizes the modification.•The hydrophilicity of hydrophobic PVDF membrane is greatly improved.•Modified membranes show excellent oil repel and antifouling properties.
