荷电镶嵌膜的研究进展

Progress on the Research of Charged-mosaic Membrane

荷电镶嵌膜主要用于无机盐与低分子量有机物的分离。本文简要介绍了荷电镶嵌膜及其制备原理、近二十年来荷电镶嵌膜的研究进展和发展动态。荷电镶嵌膜的制造主要有嵌段共聚、接枝改性、界面聚合、共混等方法。荷电镶嵌膜的研究热点主要集中在提高荷电镶嵌膜的荷电容量、控制膜内正负荷电基团的比例、深化研究荷电镶嵌膜的传递机理、表征技术和工业应用等方面。

The chargedmosaic membrane is mainly used to separate electrolytes and organics with low molecular weight. The principles of chargedmosaic membrane fabrication, the progress and the frontier of the membrane research in last twenty years were briefly introduced in this paper. Essential methods for preparing chargedmosaic membranes, such as the multiblock copolymers, graft modifications, interfacial polymerization and copolymer blending etc., were elaborated in detail. Future research of the membrane would concentrate on how to increase capacities of the charged groups, control percentages of the groups and reinforce the study on ions transfer mechanism, membrane characterization and its industrial applications.
