Abstract
The electrochemical oxidation of 2-aminobenzothiazole, 2-ABT, on Pt-electrode has been investigated using CV in HCl solutions under nitrogen atmosphere at different temperatures, different monomer concentrations and different Na2SO4 concentrations. The experimentally obtained kinetic equation was R-P,R-E = k(E) [monomer] (1.19) [acid] (1.32) [electrolyte] (1.08), which was deduced from values of the first anodic current density (i(pI)). A simplified mechanism for the electrochemical oxidation of 2-ABT is proposed. Activation energy, which was obtained from the experimental data, was almost same in studied parameters. This means the electrochemical oxidation mechanism for 2-ABT must be the same. The obtained polymer films are found to be thermally stable and have tubular or fibrillar elongated crystals. Different tools have been used to characterized P(2-ABT) as: H-1 NMR, Uv-vis, IR spectroscopy and elemental analysis.
