| 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%. |
