  • The polyacrylonitrile (PAN)/polypyrrole (PPy) composite films have been prepaxed by exposing the PAN films containing oxidizing agent such as ferric chloride or cupric chloride to pyrrole vapor. The formation of PPy in PAN was confirmed by means of IR spectroscopy and scanning electron microscopy and the X-ray differaction study showed the amorphous structure of PPy. The breaking strength of PAN/PPy composite films was 3-5 times lower but the breaking elongation of them was 4-5 times higher than that of PAN film.
