Electrochemical Characteristics of an Insulating Polymer-Modified Electrode Prepared by Electrochemical Polymerization

The electrochemical polymerization of 1,4-bis(2-methylstyryl)benzene and the electrochemical behavior of the resulting polymer-modified electrode have been studied. The rapidly decreasing polymerization current of the 1,4-bis(2-methylstyryl)benzene can be attributed to the passivation effect of the resulting polymer coating. The polymer-modified electrode showed an electrochemical response in an aqueous electrolyte solution corresponding to solute electroactive ions. The electrochemical behavior was dependent on the polymerization charge and the size of the electroactive ions. The polymer-modified electrode is applicable as the selective electrode for electroactive ions and molecules in an electrolyte solution containing electroactive bacterial cells.
