Polyelectrolyte membranes made of poly(perfluorocyclobutanes) with pendant perfluorosulfonic acid groups and blends with poly(vinylidene fluoride)

摘要

A polymer useful as an ion conductor in fuel cells includes a perfluorocyclobutyl moiety and pendant PFSA side groups. The polymer is made by a variation of the Ullmann reaction. Ion conducting membranes incorporating the polymer are provided.
