以聚丙烯腈静电纺丝膜为基膜,哌嗪(PIP)和均苯三甲酰氯(TMC)为单体,采用界面聚合法制备新型的复合纳滤膜,并对其性能进行了表征.实验重点研究了界面聚合中参加反应单体的浓度对界面聚合的影响.并用表面全反射红外光谱(ATR-FTIR)和扫描电镜(SEM)分别对界面聚合前后膜表面化学组成和膜表面、断面的微观结构进行了表征.最后还对复合膜的分离性能进行了测试,在0.3 MPa、25℃条件下,膜的纯水通量为14 L/(m2· h),复合膜对2 000 mg/L NaCl和Na2 SO4以及10 mg/L的固绿和甲基橙小分子的截留率分别为27.92％、95.13％、93.59％和95.81％,达到了纳滤分离级别.
