摘要
Six highly fluorinated poly(arylene ether)s were prepared by using a nucleophilic polycondensationreaction and their sulfonation selectivity was investigated.Single site of each repeated unit on pendant phenylgroup could be obtainedviathe postsulfonation approach under mild reaction conditions.Phenylated fluorina-ted poly(arylene ether)(Ph-FPAE) showed more excellent controllability over substituted sites and sulfonationdegree when chlorosulfonic acid was used as sulfonation reagent.The resulting sulfonated Ph-FPAE(Ph-SF-PAE) exhibited good thermal stability,solubility and hot-water dimensional stability,and also had a protonconductivity of 0.10 S/cm at 100℃.The results showed that Ph-SFPAE might be a candidate material forproton exchange membrane in fuel cell applications.
Six highly fluorinated poly （arylene ether）s were prepared by using a nucleophilic polycondensation reaction and their sulfonation selectivity was investigated. Single site of each repeated unit on pendant phenyl group could be obtained via the postsulfonation approach under mild reaction conditions. Phenylated fluorinated poly（ arylene ether） （Ph-FPAE） showed more excellent controllability over substituted sites and sulfonation degree when chlorosulfonic acid was used as sulfonation reagent. The resulting sulfonated Ph-FPAE （Ph-SFPAE） exhibited good thermal stability, solubility and hot-water dimensional stability, and also had a proton conductivity of 0. 10 S/cm at 100 ℃. The results showed that Ph-SFPAE might be a candidate material for proton exchange membrane in fuel cell applications.
