摘要
将氯甲基化聚砜(CMPS)超滤膜浸泡于三甲胺水溶液中制得季铵化聚砜(QMPS)超滤膜。本文就一些反应条件对季铵化聚砜超滤膜性能的影响进行了探讨,同时对季铵化聚砜超滤膜和氯甲基化聚砜超滤膜的形态结构作了对比,并研究了它们的亲水性能和电性能等方面的差异。
Quaternized polysulfone (QMPS) UF membrane could be made through dipping chloromethylated polysulfone (CMPS) into solution of trimethla-mine. In this paper, effects of quaternized reaction condition on the properties of quaternized polysulfone UF membrane were studied.The hydrophilic and electric properties as well as the morphological structures of QMPS and CMPS UF membranes were contrasted also.
