▎ 摘　　要

In this present work, a facile approach of fabricating thin-film composite nanofiltration membranes was proposed by introducing a graphene oxide (GO)@poly(dopamine) (PDA) interlayer, which was conducted by dopamine self-polymerization and amino/acyl chloride interfacial polymerization. It could be found that the presence of a GO@PDA interlayer had a significant influence on the polyamide formation including polyamide topography, thickness, hydrophilicity, and separation performance. Under the optimum conditions, the designed membrane exhibited a pure water flux of 11.4 L.m(-2).h(-l).bar(-1) (0.8 MPa, 25 degrees C) and high salt rejections of different salts with the order Na2SO4 (98.22%) > MgSO4 (97.76%) > MgCl2 (84.05%) > NaCl (66.99%). In addition, the modified membrane displayed excellent anti-fouling property and structural stability. As a summary of the finding in this work, it is expected to contribute a strategy on the fabrication of nanofiltration membrane with good performance, which will exhibit a high potential of industrial application.
