以聚砜(PSF)中空纤维超滤膜为基膜,2,2-二(1-羟基-1-三氟甲基-2,2,2-三氟乙基)-4,4-亚甲基双苯胺(BHTTM)为水相单体,均苯三甲酰氯(TMC)为有机相单体,采用界面聚合方法制备了中空纤维复合纳滤膜,分析了基膜和纳滤膜的微观结构、表面粗糙度、红外光谱和亲水性,讨论了不同反应时间、热处理时间、单体浓度等制备条件对纳滤膜性能的影响.结果表明,当水相1％ (w/v) BHTTM、油相0.15％ (w/v) TMC和界面聚合时间10 s,并在60℃下热处理10 min时,所得纳滤膜具有良好的分离性能,对于无机盐的截留率大小顺序均为Na2SO4＞MgSO4＞NaCl＞MgCl2,纳滤膜表面带负电.
