Abstract

Supported liquid membranes (SLM) offer promise of improved molecular and ionic transport in polyelectrolyte membranes (PEM), key components in batteries and fuel cells. Incorporation of ionic liquids (IL) into PEM has demonstrated increased molecular and ionic transport, and it is probable that liquid polymerized ionic liquids (LPIL) also will benefit such PEM properties. Herein we demonstrate preparation of LPIL copolymers that have suitable functionality for tethering such LPIL to SLM. We uncover a design principle for producing LPIL, wherein liquid homopolymers that are precursors for PIL are partially modified and converted into LPIL. We show that the homopolymer poly(bromoundecyl acrylate), poly(AcOC₁₁H₂₂Br), is such a liquid precursor. We explore conversion of this homopolymer into LPIL by using it to alkylate 1-methyl imidazole.
