摘要/Abstract

摘要： 以丙烯酰胺接枝的聚丙烯(PP)超滤膜为支撑层，间苯二胺(MPD)、均苯四甲酰氯(BTAC)分别为水相及有机相功能单体，通过界面聚合及其后续的酰亚胺化制备了聚酰亚胺(PI)/PP耐溶剂复合纳滤膜。讨论了水相浓度、有机相浓度及酰亚胺化溶液配方等条件对复合膜结构及其分离性能的影响。分别采用傅里叶红外光谱仪(FTIR)、扫描电子显微镜(SEM)表征分离层的化学组成及复合膜的形态结构，得到膜的分离、透过及其耐溶剂性能。结果表明，有机相浓度的影响最为显著，支撑膜表面形成了均匀致密的PI分离层，复合膜呈负电性，并具备优秀的耐溶剂性能。实验范围内，MPD、BTAC的浓度分别为8、2 g·L-1，酰亚胺化溶液乙酸酐∶三乙胺∶苯体积比为1∶1∶10时，所制备膜的分离性能较佳，对Na2SO4、酸性艳蓝6B的截留率分别达93.8%和96.9%。

Abstract: A novel polyimide(PI)/polypropylene(PP)solvent resistant nanofiltration(SRNF)composite membrane was prepared by interfacial polymerization(IP)of metaphenylene diamine(MPD)with 1,2,4,5-benzene tetra acyl chloride(BTAC)on the surface of acrylamide grafted PP support.The effects of monomers concentration，ratio of imidizing solution were investigated.The chemical composition of barrier layer and morphology of the resulting membrane were characterized with Fourier transform infrared spectra(FTIR)and scanning electronic microscopy(SEM)，respectively.The rejection，permeation and solvent resistant performance of the resulting membranes were also determined.An orthogonal experiment showed that BTAC concentration was the first affecting factor.A non-defective fine PI selective layer was formed on the PP support，and the resulting membrane presented a negatively charged behavior.The optimized conditions were as follows：concentration of BTAC and MPD 2 g·L-1，8 g·L-1 respectively，and volume ratio among acetic anhydride，triethylamine and benzene in imidizing solution 1∶1∶10.Under an operating pressure of 0.5 MPa，the rejection rates of the resulting membrane to Na2SO4 and acid brilliant blue 6B were 93.8% and 96.9%，respectively.
