| titleOfInvention | Fluorine-containing polyarylether anion exchange membrane containing tri-quaternary ammonium salt side chain and preparation method thereof |
| abstract | The invention relates to a fluorine-containing polyarylether anion exchange membrane containing tri-quaternary ammonium salt side chains and a preparation method thereof. The invention firstly carries out polycondensation reaction on 4, 4' - ((2,3,5, 6-tetra (3, 5-dimethylphenoxy) -1, 4-phenylene) bis (oxy)) diphenol monomer, bisphenol A and decafluorobiphenyl at room temperature to prepare the fluorine-containing polyarylether compound, and then uses N Brominating the raw material by bromosuccinimide, reacting the brominated raw material by a tertiary amine compound containing biquaternary ammonium salt to prepare a fluorine-containing polyarylether compound containing tri-quaternary ammonium salt side chains, and finally preparing the fluorine-containing polyarylether anion exchange membrane containing tri-quaternary ammonium salt side chains by a solution casting method. The anion exchange membrane has the advantages of high oxidation stability, high ionic conductivity, low vanadium ion transmittance, good mechanical property and the like, and can be used as an excellent all-vanadium redox flow battery diaphragm. |
