Poly(ionic liquid)s(or polymerized ionic liquids

PILs)are defined by the polyelectrolytes generated from ionic liquid monomers

with cations and anions in the repeating units. PILs combines the advantages of both ionic liquids and polymers. Researches work on designing and synthesizing the new and stable materials with specific functions based on the designability of PILs molecules. The functional PIL materials have been preliminarily applied in the fields of polymer chemistry

electrochemistry

energy and material science recently. This review introduces and discusses the new applications of poly(ionic liquid)s

including solid-state electrolyte

polyelectrolyte membrane

smart responsive materials

PILs/carbon hybrid materials

carbonaceous material derived from poly(ionic liquid)s and catalysis.
