Abstract

 

         For the first time, the possibility of overoxidized polypyrrole N-oxidation has been investigated from the theoretical point of view. The correspondent mathematical model has been developed and analyzed by means of the linear stability theory and bifurcation analysis. It was shown that the polypyrroleoveroxidation in the presence of peroxide compounds or at a slightly higher potential will yield a N-oxidized form, and its formation will be accompanied by the enhance of the oscillatory and monotonic instability realization probability. This enhance is among the factors, defining the resulting polymer morphology and conductivity.
