| 英文摘要 | Hydrophilic nanofiltration membranes with single-layered or double-layered poly(ethylene glycol) (peg) based structure were fabricated by two-step interfacial polymerization (ip) to enhance antifouling property. o,o'-bis(2-aminopropyl) polypropylene glycol-block-polyethylene glycol-block-polypropylene glycol (jeffamine) was used as monomer and modifier in both layers. the antifouling performance against bovine serum albumin (bsa) for the nascent polyamide membrane with single peg-based layer was not satisfactory with a highest water flux recovery ratio (frr) of 75.9%. therefore, a second ip was performed between jeffamine and the residual unreacted chloroformyl group in selective layer to form an additional peg-based layer, which demonstrated the two-end-linked structure when jeffamine 2003 was used and the linear suspension structure when jeffamine 600 was used. the results showed that the flux and rejection of membranes with double-layered peg-based structure had little variation compared with that of single-layered membranes, while the antifouling performance against bsa was significantly improved by the additional peg-based layer. moreover, the additional linear suspension peg-based layer contributed more to antifouling performance than the additional two-end-linked peg-based structure. the membrane with the additional linear suspension peg-based layer displayed a highest water frr of 99.6%, while the membrane with the additional two-end-linked peg-based layer displayed a highest water frr of 83.6%. |
