摘要：
The modified membrane GO-Ag/PVDF was fabricated usingco-polymer F127 and nanocomposite GO-Ag as functional additives via non-solvent induced phase separation (NIPS) method for natural organic matter (NOM) resistance. Due to the introduction of co-polymer F127 and nanocomposite GO-Ag, resultant membranes exhibited excellent hydrophilicity and permeability. Meanwhile, the modified membrane surface showed better fouling resistance to natural organic matter (NOM) and bacteria compared with pristine membrane. In summary, the membrane MF1825 under the optional additive combination possessed the better performance with pure water flux of 821L.m(-2)h(-1) and the contact angle of 62(o) comparing the membrane MF1800 with pure water flux of 14 L.m(2).h(-1) and the contact angle of 80(o). In addition, the membrane MF1825 had the improved fouling resistance order to NOM models: BSA > SA > HA, which indicated a potential application in natural organic water treatment.
