中文摘要	we report an effective and simplified procedure for the synthesis of cross-linked alkaline anion-exchange membranes (aems). a new monomer containing two tertiary amine groups on 4,4'-dihydroxydiphenyl ether (dabpe) is used in nucleophilic aromatic substitution step-growth copolymerization with 4,4'-difluorobenzophenone, 2,2',6,6'-tetramethyl-4,4'-biphenol to obtain the corresponding poly(arylene ether ketone) copolymers containing tertiary amine groups. after partial quaternization, the residual tertiary amine groups of the polymer react with p-xylylene dichloride to produce a cross-linked membrane, which is followed by anion exchange with hydroxide ions. the resulting cross-linked membranes exhibit high hydroxide ion conductivity (above 10(-2) s cm(-1) at room temperature), good mechanical properties, and reduced water uptake relative to the linear uncross-linked membrane. this facile synthetic approach enables the preparation of cross-linked materials with the potential to meet the demands of hydrogen-powered fuel cells as well as direct methanol fuel cells.
