Abstract
Two series of novel sulfonated poly(arylene ether phosphine oxide)s were synthesized by incorporating cheap bisphenol A or bisphenol AP into the backbone via direct polycondensation. Both sulfonated poly(arylene ether phosphine oxide)s could be cast into uniform and ductile membranes. Their properties as proton exchange membranes were investigated and compared in detail. As a result, the sulfonated poly(arylene ether phosphine oxide)s containing bisphenol AP units show better properties than polymer containing bisphenol A units with similar ion exchange capacity (IEC). For example, the former membrane shows a XY swelling ratio of 9.8%, a Z swelling ratio of 9.5%, a proton conductivity of 0.084 S/cm and 100% residual weight after immersing in Fentons’ reagent for 1 h at 80°C. Therefore, it is a promising proton exchange membrane for fuel cell due to cheap and high performance.
期刊介绍：
Polymer Science, Series B is a journal published in collaboration with the Russian Academy of Sciences. Series B experimental and theoretical papers and reviews dealing with the synthesis, kinetics, catalysis, and chemical transformations of macromolecules, supramolecular structures, and polymer matrix-based composites (6 issues a year). All journal series present original papers and reviews covering all fundamental aspects of macromolecular science. Contributions should be of marked novelty and interest for a broad readership. Articles may be written in English or Russian regardless of country and nationality of authors. All manuscripts are peer reviewed
