Advanced research and prospects on polymer ionic liquids: trends, potential and application

The purpose of this short perspective review is to summarize the recent literature on the main trends in the use of polymer ionic liquids (PILs) published in the period from 2021 to 2023. Only the most promising areas that will play crucial roles in the very near future are considered. These areas include, in the authors' opinion, the biochemical and medical applications of PILs; sorption and separation of gases and liquid-phase sorption; solar cells; chemical sensors, supercapacitors and polymer transistors; and catalysts (including electro- and photocatalysts). The advantages of and approaches for improving the efficiency as well as the green approach for the synthesis and use of PILs are discussed.
