Kinetics of the electrochemical doping processes

In order to evaluate conducting polymers as possible electrode materials for novel devices, it is essential to investigate the kinetics of the doping processes. 

As is well known in the field of electrochemistry in general, electrode kinetics may be conveniently examined by cyclic voltammetry (CV) and by frequency response analysis (ac impedance). The kinetics of the various polymer electrodes considered so far in this chapter will be discussed in terms of results obtained by these two experimental techniques.

Considerable attention is presently devoted to heterocyclic polymers, such as polypyrrole, polythiophene and their derivatives. The kinetics of the electrochemical doping processes of these polymers has been extensively studied in electrochemical cells using non-aqueous electrolytes.
