Conductive polypyrrole-cellulose acetate films were prepared from cellulose acetate (CA) solution of pyrrole (Py) using wet cast method. In the composite films, Py was used as a solvent for CA which was dissolved with different concentration. Then, to prepare PPy-CA composite film, the Py viscous solution of CA was cast on glass plate and immersed in FeCl3 aqueous solution. When the CA film was formed in the aqueous solution, the polymerized PPy particles having about 1 m diameter were formed in composite film. The resultant composite films were characterized, showing good film fabrication and electrical conductivity of around 6.9 x 10(-4) to 3.6 x 10(1) S/cm. POLYM. ENG. SCI., 54:78-84, 2014.
