【摘要】：复合纳滤膜凭借其效率高与能耗低的特点在分离膜领域占据着越来越重要的地位. 但其制备所面临的最大挑战在于如何实现选择性皮层构建过程及结构性能的有效调控.通过"可控"的表界面工程可以实现对界面性质及界面反应速率的调控,从而实现复合纳滤膜的可控制备和性能提升.因此,我们提出通过""可控"聚合-界面沉积"构建选择性皮层以实现复合纳滤膜分离层的创新制备和多功能化、基于"基膜-单体溶液界面构建"调控界面聚合以获得更薄分离层和更优异的纳滤性能.本文总结和评述了基于"可控"表界面工程的聚合物纳滤膜的重要进展,分析了该领域的未来研究方向,旨在为高性能复合纳滤膜的可控制备提供系统的方法学及理论支持.
[Abstract]:Composite nanofiltration membrane plays a more and more important role in separation membrane field because of its high efficiency and low energy consumption. However, the biggest challenge in preparation of composite nanofiltration membrane is how to realize the effective regulation of selective cortex construction process and structure and performance.Through "controllable" surface interface engineering, the interface properties and reaction rate can be controlled, thus the controllable preparation and performance improvement of composite nanofiltration membrane can be realized.Therefore, we propose to construct selective cortex by "controllable" polymerization-interface deposition to achieve the innovative preparation and multifunction of composite nanofiltration membrane separation layer.Interfacial polymerization is regulated based on "substrate film-monomer solution interface construction" to obtain thinner separation layer and better nanofiltration performance.This paper summarizes and reviews the important progress of polymer nanofiltration membrane based on "controllable" surface engineering, and analyzes the future research direction in this field, aiming at providing systematic methodological and theoretical support for the controllable preparation of high performance composite nanofiltration membrane.
