Abstract


Electrochemical polymerization of aniline was carried on platinum (Pt) wire electrode in sulfuric acid (H2SO4) solution by cyclic voltammetry using a conventional three-electrode cell at room temperature (20°C). The effects on the electrodeposition of the monomer concentration, anodic potential and potential scan rate are discussed. The conductive layer of emeraldine base polyaniline (Pani) was prepared in this work by repeating potential cycling between -0.24 and 0.9 V/SCE at 50 mV/s in 1 M H2SO4 solution containing 0.1 M aniline monomer.
