Ionic liquids and polymeric ionic liquids as stimuli-responsive functional materials

Abstract

The anion recognition-based stimuli responsiveness of ionic liquids (ILs) and polymerized ionic liquids (PILs) is presented in the context of various association structures formed by these functional materials, and their responsiveness is characterized by ordered Hofmeister series. Gels and gelation, critical solution temperatures, and diverse applications including dispersion phase transfer and osmotic sphere and osmotic brush stabilization are discussed and illustrated.
