Electrochemical Deposition Mechanism of Polyaniline at High Potential in Organic Electrolyte
Polyaniline (PANI) was deposited on the glassy carbon electrode in organic electrolyte. The deposition mechanism and properties of resulted PANI were characterized with Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), Electrochemical Impedance Spectroscopy (EIS). The results show that: the polymerization of PANI can carry in a relatively high potential (2.4V), and the electrochemical deposition mechanism of PANI at high potential in organic electrolyte is different from that in inorganic system due to the low conductivity and diffusion coefficient of organic electrolyte. The electro-conductivity of PANI is good in the range of 0.2~0.8V which is wider than that reported in inorganic electrolyte.
