Influence of counter ions in electrochemical properties and kinetic parameters of poly tyramine electroactive film

This work present that the electrodeposited poly tyramine (PTy) film by using potentiostatic method on the surface of the graphite electrode is fractal object with semiconductor properties. Electrosynthesized polymers in the presence of the different anions have been characterized by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The effect of different anions and electrosynthesis parameters on the morphology, kinetic parameters and fractal dimension of the polymer was evaluated. Diffusion coefficient of counter ions calculated from the slope of the Warburg line in the Nyquist plot. A value of gamma that is the characteristic of anomalous diffusion is obtained by EIS method and then the relation between fractal dimension and anomalous diffusion has been investigated.
