Abstract:

Poly(2-methoxyaniline) (PMOA) was electrosynthesized with varying monomer concentrations in 1 M HClO4. The polymers obtained were characterized using cyclic voltammetry, Fourier transform IR diffuse reflectance spectroscopy (FTIR-DRS), UV-vis spectroscopy and electrochenlical impedance. At relatively high monomer concentrations (>20 mM), the polymer obtained is similar to aryl amine conducting polymers, but shows in its voltammogram an intermediate peak, which becomes larger as the monomer concentration decreases. For monomer concentrations below approximately 20 mM, the polymer becomes more resistive, behaving similarly to aryl amine redox polymers. The different techniques employed show results consistent with the voltammetric experiments. This change of behaviour indicates that different polymers are obtained as the monomer concentration is modified.
