Abstract
Methods of preparing reinforced anion exchange membranes are provided, as well as produced membranes and corresponding devices utilizing the membranes. Methods comprise compounding a halide-functionalized polymer (selected to react with amines to yield anion-conducting quaternary amine groups) with thermoplastic polymer(s) (selected to support and/or reinforce the membrane), and with copolymer(s) (selected to enhance the compounding of the polymers)—by heating, mixing and cooling—to form blend pellets, extruding the blend pellets to form a blend film, cross-linking polymer(s), and functionalizing the blend film to prepare the anion exchange membrane. Functionalization comprises a quaternization step comprising reacting halogen groups of the first polymer with tertiary amines to produce the quaternary amine groups with ion-exchange functionality. Reinforced anion exchange membranes are provided, which are produced by the disclosed methods, functionalized to yield a membrane for fuel cell(s), electrolyzer(s), reversible electrochemical device(s), desalination unit(s), etc.
