摘要: Abstract A series of novel tetra-quaternized poly(arylene ether ketone)s (QPAEK- x ) with high densely quaternized pendants are investigated in this work. As polymer electrolyte precursors, the four benzyl units containing prepared from 4,4′-difluorobenzophenone, 4,4′-(hexafluoroisopropylidene) bisphenol and designed monomer. Then, objective ionomer is successfully obtained via free-radical bromination, followed by quaternization ketone)s. These anion exchange membranes show excellent dimensional stability, adequate thermal stability hydroxide conductivity, owing to pendent quaternary ammonium structures concentrated on side chain. The highest conductivity (0.0653 S cm −1 appears QPAEK-0.8 (IEC=1.69 mmol g ), swelling ratio length 11.7% at 80 °C. suitable morphology using SAXS, which should be a possible reason for enhancement.
