Electropolymerization of Methylene Blue on Highly Oriented Pyrolytic Graphite and Characterization of Deposited Film

Abstract

This work presents the investigation of methylene blue (MB) polymerization as well as characterization of deposited conductive film on basal plane highly oriented pyrolytic graphite (HOPG) substrate. Poly(methylene blue) modified HOPG electrodes (HOPG/pMB) have been prepared by potential cycling in aqueous electrolyte solution containing monomer methylene blue.

Atomic force microscopy (AFM) has been used for the nanomorphological study of immobilized poly(methylene blue) film.
