Abstract

• The effects of monomers on the electrically conductive polymer films were studied. In the preparation of conductive film, pyrrole (Py) and formyl pyrrole (FPy) were used as the source of monomers. Trifluoroacetic acid (TFA) and chloroform were utilized as a catalyst and solvent. One of the synthesis parameters, mole fractions of FPy against Py, was systematically varied from 0.1, 0.3, 0.5, 0.7 to 0.9 respectively. Then, the effects of monomers on the electrical properties of obtained conductive polymer films were studied. The formation of film was characterized and confirmed by ultraviolet-visible(UV-vis ), X-rays diffraction (XRD) and Fourier transform infrared spectrometry(FTIR). Frequency dependent electrical conductivity of the prepare film is increased with the increasing mole fraction of FPy.
