Polyacrylonitrile‐polypyrrole composite films were prepared by a vapor phase technique. The films obtained by this method have high conductivity and good mechanical properties. Growth of polypyrrole on the surface of polyacrylonitrile was investigated by electron microscopic studies. Electrical properties of composite films were investigated as a function of FeCl 3 content as well as polypyrrole uptake. The current‐voltage characteristic suggest an ohmic conduction. The conductivity of these composite films was measured as a function of temperature yielding an activation energy of 0.16 eV.
