Cross-linked comb-shaped anion exchange membranes with high base stability

Author affiliations

Abstract

A unique one-step cross-linking strategy that connects quaternary ammonium centers using Grubbs II-catalyzed olefin metathesis was developed. The cross-linked anion exchange membranes showed swelling ratios of less than 10% and hydroxide conductivities of 18 to 40 mS cm−1. Cross-linking improved the membranes' stability to hydroxide degradation compared to their non-cross-linked analogues.
