Abstract
The coating of polypyrrole (PPy) on steel gauze electrode by electropolymerization of pyrrole with voltammetry cyclic method has been investigated. The purpose of this research is a preliminary study the character of a steel gauze as working electrode which potential to electrodeposition on Polypyrrole (PPy) film based on literature. Based on cyclic voltammogram of PPy, the oxidation potential has been achieved at a potential range of 0V to 1V which compared to Ag/AgCl as reference electrode at a anodic peak current (Ipa) near 7 mA at a scan rate 100 mV/sec from a solution 0.05M of Py in the solution 0.1M of KCl as supporting electrolyte. The competition between PPy with some major component of steel gauze such as Fe, Zn, Cr or Mn occured, in the potential range 0 to 1V during the electropolimerization. The main component of steel gauze has been analyzed by X-Ray Fluoresence (XRF). PPy films can cover the surface of steel gauze with the number of ten cycles of polymer growth on the electrode surface have been studied with the anodic and cathodic peak current with the correlation coefficient 0.999 and 0.991 of the increasing the number of cycles at the potential range of 0.2V to 0.8V. The results of PPy film on the steelgauze electrode has been characterized by Fourier Transform Infra Red (FT-IR). Keywords: Steel gauze, Polypyrrole, Electropolymerization, Cyclic voltammogram, Cyclic voltammetry.
