H-bonded composite membranes were prepared from SPPENK, SPPESK and SPPBEK, respectively, and polyetherimide (PEI). Both of Compounds were dissolved in N-methylpyrrolidone (NMP), and tough membranes were obtained by casting from NMP solution with 9:1 mass ratio of sulfonated poly(phthalazinone ether)s/PEI. These H-bonded composite membranes all showed better thermal, oxidative and mechanical stabilities than corresponding pure sulfonated polymers membranes. The H-bonded composite membranes had high proton conductive ranging from 0.02 to 0.06 S/cm at 95 degrees C. All membranes showed an increase in proton conductivities with temperature elevation. The swelling ratio of H-bonded composite membranes was lower than that of pure membranes. (C) 2007 Elsevier B.V. All rights reserved.
