Abstract
In this work, electrically conductive polyetherimide(PEI)-polypyrrole(PPy) composites have been prepared and their electrochemical properties were investigated. The composites were prepared on indiumtin-oxide(ITO) coated glass electrode. The composite films showed lower conductivity but better thermal stability than PPy homopolymer film. The properties of the composite films were strongly dependent on the preparation method of the PET matrix.
