Poly(ionic liquids) membranes preparation and its application

Poly(ionic liquids)(PILs) not only possess unique properties such as the flexibility of ionic liquids (ILs) but also feature the macromolecular structure of polymers, which makes them a series of functional polymers with special properties and new applications. Poly(ionic liquids) membranes(PILMs) have come into the limelight because of their powerful mechanical property, excellent stability, high water flux and good selectivity. This paper mainly reviews the preparation methods of PILMs and presents the advantages, discusses the properties of PILMs and summarises the affecting factors, and finally introduces applications of PILMs. In addition, the coming research direction of PILMs is demonstrated.
