Abstract
Polypyrrole/ polyaniline (PPy/PAn) composite films have been prepared by direct electrochemical polymerization of pyrrole in an aqueous solution of PAn. Spectroscopic results demonstrated that the polyanion, PAn, was incorporated into the PPy matrix as a dopant. The composite films exhibited a higher thermal stability than that of pure PPy. Scanning electron microscopic images revealed that the composite film had smooth and compact morphology.
