Synthesis of polymer ionic liquids and ionene-type ionic liquids

Abstract

The synthesis of polymer ionic liquids and ionene-type ionic liquids has been optimized through the implementation of a rigorous scientific and methodical approach. The feasibility of utilizing an integrated "polymer–monomer" strategy for synthesizing polymer ionic liquids has been demonstrated. The concentration-dependent viscosity of ionene-type polymer ionic liquids in solutions was analyzed, and the influence of their chemical nature was elucidated. Practical recommendations have been developed to address the scientific and applied challenges associated with creating new ionene-type polymer ionic liquids that exhibit high ionic conductivity while maintaining a liquid state over a wide temperature range. These findings aim to solve pressing issues in chemical technology.
