Abstract


The electrochemical behavior of the system with the anodic overoxidation of conducting polymers was described mathematically. The balance equation system describing it was analyzed using the linear stability theory and bifurcation analysis. The stable steady-state conditions and oscillatory instability conditions were found.

Keywords


conductive polymers; polypyrrole; polythiophene; overoxidation; oxidative degradation
