THE GALVANOSTATIC AND POTENTIODYNAMIC (IN CONSTANT VOLTAGE MODE) ELECTROPOLYMERIZATIONS OF HETEROCYCLIC COMPOUNDS. THE PROCESSES AND THEIR MATHEMATICAL DESCRIPTION

Abstract

The electrochemical processes of the anodic electropolymerization of heterocyclic compounds in galvanostatic and potentiodynamic constant-voltage mode, realized to obtain the corrosion-protecting coatings, are mathematically described. The correspondent mathematical models, by using the linear stability theory and bifurcation analysis, are analyzed. The experimentally observed electrochemical instabilities in the conditions of the models are explained.
