Abstract:

The sub-nanometer high-precision separation of molecules/ions by confined mass transfer separation membranes is a hot topic and difficulty in the current membrane research field. Clarifying the confined mass transfer effect within the membrane, forming a common mass transfer mechanism and manipulation methods, is a key way to break through the trade-off effect and achieve extraordinary membrane separation performance. This article reviews the research progresses of confined mass transfer separation membranes in recent years from three aspects: the construction of confined mass transfer channels, the confined mass transfer mechanism, and the application of confined mass transfer separation membranes. The future development direction of confined mass transfer separation membranes has also been proposed, which is expected to provide reference for the design and application of high-performance membrane materials.

Key words: confined mass transfer, sub-nanometer channels, membrane, separation, transport

摘要:

限域传质分离膜面向分子/离子的亚纳米尺度高精度分离,是目前国内外膜领域研究的热点和难点。厘清膜内的限域传质效应,形成共性传质机制及调控方法,是突破trade-off效应,实现超常膜分离性能的关键途径。从限域传质通道构筑、限域传质机理及限域传质分离膜应用三个方面入手,对限域传质分离膜近年来的研究进展进行举例介绍与讨论,并对限域传质分离膜的未来发展方向进行了思考与展望,以期为高性能膜材料的设计与应用提供参考。
