| 摘要 |
The invention relates to polymer blends and polymer blend membranes consisting of a polymer sulfonic acid and a polymer containing primary, secondary or tertiary amino groups, which are produced by premixing the sulfonic acid salt with the polymer containing primary, secondary or tertiary amino groups. The invention also relates to the use of polymer blend membranes in membrane fuel cells, polymer electrolytic membrane fuel cells (PEFC) or direct methanol fuel cells (DMFC), in membrane electrolysis, in aqueous or water-free electrodialysis, in diffusion dialysis, separation under perstraction conditions of alkenes from alkene/alkane mixtures (the membranes are present here in the form of SO3Ag, wherein the Ag+ reversibly complexes the alkene (facilitated transport)) in separation by pervaporation of water from mixtures of water/organic matter or in gas separation. |
