    摘要： The invention relates to: —anion exchange blend membranes consisting the following blend components: —a halomethylated polymer (a polymer with —(CH2)x—CH2—Hal groups, Hal=F, Cl, Br, I; x=0-12), which is quaternised with a tertiary or a n-alkylated/n-arylated imidazole, an N-alkylated/N-arylated benzimidazole or an N-alkylated/N-arylated pyrazol to form an anion exchanger polymer. —an inert matrix polymer in which the anion exchange polymer is embedded and which is optionally covalently crosslinked with the halomethylated precursor of the anion exchanger polymer, —a polyethyleneglycol with epoxide or halomethyl terminal groups which are anchored by reacting with N—H-groups of the base matrix polymer using covalent cross-linking—optionally an acidic polymer which forms with the anion-exchanger polymer an ionic cross-linking (negative bound ions of the acidic polymer forming ionic cross-linking positions relative to the positive cations of the anion-exchanger polymer)—optionally a sulphonated polymer (polymer with sulphate groups —SO2Me, Me=any cation), which forms with the halomethyl groups of the halomethylated polymer covalent crosslinking bridges with sulfinate S-alkylation. The invention also relates to a method for producing said membranes, to the use of said membranes in electrochemical energy conversion processes (e.g. Redox-flow batteries and other flow batteries, PEM-electrolyses, membrane fuel cells), and in other membrane methods (e.g. electrodialysis, diffusion dialysis).

    摘要： The invention relates to organic/inorganic hybrid polymer blends and hybrid polymer blend membranes that are composed of: one polymer acid halide containing SO2X, POX2 or COX groups (X═, Cl, Br, I); one elemental or metallic oxide or hydroxide, obtained by the hydrolysis and/or the sol/gel reaction of an elemental and/or organometallic compound during the membrane forming process and/or by subsequently treating the membrane in aqueous acidic, alkaline or neutral electrolytes. The invention further relates to hybrid blends and hybrid blend membranes containing polymers that carry SO3H, PO3H2 and/or COOH groups, obtained by aqueous, alkaline or acidic hydrolysis of the polymer acid halides contained in the polymer blend or the polymer blend membrane. The invention also relates to methods for producing the inventive hybrid blends and hybrid blend membranes.
