    Permeability of polypyrrole film for pyrrole and methanol

  • Original language description

    Diffusion method has been proved to be a viable method of PPy fixation on the NafionŇ membrane surface. NP composites prepared have shown homogeneous morphology, very good adherence to the membrane surface and high electrochemical activity. As it was found, PPy represents an efficient barrier against methanol permeation through the composite. Its permeability for Py as well as for methanol is approximately two orders of magnitude lower when compared to the self standing Nafion# membrane. This may represent a serious problem during polymerisation of the secondary PPy layer. It has been solved by means of electropolymerisation of PPy film of necessary thickness on the top of chemically presynthesised sublayer.
