聚电解质层层自组装制备PV、NF膜研究进展

Progress in preparation of pervaporation and nanofiltration membranes by self-assembly of polyelectrolyte

层层自组装作为一种新的膜制备技术已被人们应用于渗透汽化膜、纳滤膜等分离膜的研制中,主要介绍了基膜、聚电解质电荷密度、聚合物浓度、分子量、组装层数等因素对膜性能的影响以及近年来人们为提高组装效率所做的一些研究工作。

Layer-by-layer process is applied to prepare pervaporation and nanofiltration membranes recently.This article mainly introduced the effects of preparative conditions including substrate,charge density,polyelectrolyte concentration,molecular weight,bilayer number,and etc.on the membrane filtration performance.The research work to improve the process efficiency is also presented.
