Cross-linked highly stable anion exchange blend membrane using polyethylene glycol as hydrophilic membrane phase

摘要

The present invention includes: Anion exchange blend membranes from the following blend components: -Halomethylated polymers (tertiary or N-alkylated / N-arylated imidazoles, N-alkylated / N-arylated benzimidazoles, Or a polymer with (CH2) x-CH2-Hal in which the N-alkylated / N-arylated pyrazole is quaternized to an anion exchange polymer-embedded in an anion exchange polymer and optionally an anion exchange polymer Inactive matrix polymers that are covalently cross-linked with halomethylated precursors of-having epoxide or halomethyl end groups immobilized by reaction with basic NH groups of the covalently cross-linked basic matrix polymer Polyethylene glycol--optionally acidic polymers that form ionic crosslinks with anion exchange polymers (negative fixed acid ions are (Forms ionic cross-linking sites for positive cations of on-exchange polymers)-optionally sulfinated polymers that form covalent crosslinks with halomethyl groups of halomethylated polymers under S-alkylation of sulfinates Polymers with acid groups-SO2Me, Me = any cation)-Preparation processes for these membranes-Electrochemical energy conversion processes (eg redox flow cells and other flow cells), PEM electrolysis, membrane fuel cells, and other Use of these membranes in membrane processes (eg electrodialysis, diffusion dialysis).
