Synthesis of Sulfonated Fluorenyl-containing PEEKK and Its AMPH-POSS Hybrid Membranes

doi:10.3969/j.issn.0251-0790.2012.06.001

Abstract

Abstract: Fluorenyl-containing sulfonated poly(ether ether ketone ketone) was synthesized through a post-sulfonation method as the matrix, and AMPH-POSS was selected as filler to form acid-base enhanced proton exchange membranes by solution casting. The microstructure and some basic properties were investigated. The filler was well dispersed in the polymer matrix. The hybrid membranes exhibited improved swelling stability, selectivity and methanol permerbilities.

Key words: Proton exchange membrane, Poly(arylene ether ketone)s, Octaminophenyl polyhedral oligomeric silsesquioxane(POSS), Hybrid
