Abstract

Sulfonated poly (ether ether ketone) membranes were obtained by the phase inversion process. These membranes were modified with chemically in situ polymerized polypyrrole in order to increase the ionic conductivity and to prevent the methanol crossover. For improving the polypyrrole ionic conductivity, this was activated with iron chloride and cerium sulfate. The new synthesized sPEEK/Ppy composite membranes were characterized by FT-IR spectroscopy, Scanning Electron Microscopy, Energy dispersive X-ray spectroscopy (EDAX), permeation measurements and the ionic conductive properties were evaluated by Electrochemical Impedance Spectroscopy..
