Abstract

In order to realize an electrolyte membrane for DMFC having low methanol permeability, addition of ionic conductivity by the introduction of polypyrrole into engineering polymers was attempted. By the chemical oxidation of pyrrole monomer inside the polymer matrix, the composite films of polypyrrole (PPy) and engineering plastics were prepared. By the PPy introduction to poly(ethyleneterephthalate) (PET) the ionic conductivity across the film was increased. Methanol permeability was also examined to assess the performance of the film as the DMFC electrolyte. The composite film of PPy/PET, which was formed by pyrrole oxidation, showed better performance of high ionic conductivity and low methanol permeability.
