The system with the electrode modification by thiourea basic derivatives for conducting polymer indirect cathodic deposition has been described from the theoretical point of view. The electrode pretreatment process has been analyzed using the linear stability theory and bifurcation analysis. It was shown that the steady-state is realized rapidly and provides efficient surface pretreatment. On the other hand, the oscillatory and monotonic behavior, in this case, is also possible due to the double electric layer capacitance changes during the doping stage and electrochemical reaction.
