不对称润湿性Janus膜的研究进展

Research Progress of Asymmetric Wettability Janus Membrane

随着现代社会的快速发展,具有均匀表面性质的传统膜由于无法满足工业生产及人类的生活所需而受到挑战,而Janus膜的出现为解决传统膜受到的挑战开辟了一条新的道路。对具有不对称润湿性的Janus膜近年来的研究进展进行了综述,重点阐述了以不同材料为基底的Janus膜如何通过不对称修饰法构建其润湿性,以及Janus膜在水的定向传输、油-水分离、雾的收集、膜蒸馏领域的应用。最后,总结了具有不对称润湿性的Janus膜目前存在的一些缺点并对未来进行了展望。

With the rapid development of modern society,traditional membranes with uniform surface properties are challenged because they cannot meet the needs of industrial production and human life.The appearance of Janus membrane opens up a new way to solve the challenge of traditional membrane.Based on this,this paper reviews the research progress of Janus membranes with asymmetric wettability in recent years.How to construct the wettability of Janus membrane based on different materials by asymmetric modification and the application of Janus membrane in directional water transport,oil-water separation,fog collection and membrane distillation are discussed.Finally,some shortcomings of Janus membrane with asymmetric wettability are summarized and the future prospect is proposed.
