The research on electro-conductive membranes has expanded in recent years. These membranes have strong prospective as key components in next generation water treatment plants because they are engineered in order to enhance their performance in terms of separation, flux, fouling potential, and permselectivity. The present review summarizes recent developments in the preparation of electro-conductive membranes and the mechanisms of their response to external electric voltages in order to obtain an improvement in permeation and mitigation in the fouling growth. In particular, this paper deals with the properties of electro-conductive polymers and the preparation of electro-conductive polymer membranes with a focus on responsive membranes based on polyaniline, polypyrrole and carbon nanotubes. Then, some examples of electro-conductive membranes for permeation enhancement and fouling mitigation by electrostatic repulsion, hydrogen peroxide generation and electrochemical oxidation will be presented.
近年来,对导电膜的研究不断扩展。这些膜作为下一代水处理厂的关键组件具有很强的前景,因为它们经过设计以在分离、通量、污垢形成潜力和渗透选择性方面提高性能。本综述总结了导电膜制备的最新进展及其对外部电压响应的机制,以实现渗透改善和污垢生长缓解。特别是,本文讨论了导电聚合物的特性以及导电聚合物膜的制备,重点是基于聚苯胺、聚吡咯和碳纳米管的响应性膜。然后,将介绍一些通过静电排斥、过氧化氢生成和电化学氧化来提高渗透和减轻污垢的导电膜实例。
