Preparation of polyaniline/polypyrrole conductive polymer films on polycarbonate-coated Pt electrodes

Abstract

In this study, free-standing polymer films were obtained first with an electrochemical coating of polyaniline and then with a coating of polypyrrole on an insulating polycarbonate-coated Pt electrode. The films contained varying amounts of polyaniline and polypyrrole obtained by varying the electrolysis time, and their conductivities were determined. The Raman spectra of the films taken from the electrode side were similar to those of pure polyaniline, whereas the spectra of the solution side were identical to those of pure polypyrrole. The resistance change in the films between -15 and +120 °C revealed that the films were sensitive to temperature.
