This research is focused on the electrochemical synthesis and characterization of
poly(methylene blue) (pMB). Two different carbon-based electrode substrates, basal plane
highly oriented pyrolytic graphite (HOPG) and pencil graphite electrode (PGE), have been
modified by conductive film of pMB. Electrochemical properties and nanomorphological
changes have been investigated by cyclic voltammetry and atomic force microscopy.
Improved electroactivity of the modified electrodes (PGE/pMB and HOPG/pMB) towards
sulfhydryl group has been observed and examined modified electrodes were researched for
their possible application in electrochemical sensor for hydrogen sulfide in aqueous solutions.
