The Effect of Supports of Glassy–Carbon and Activated Graphite Foil on the Electrochemical Behavior of Composite Coatings Based on Polyaniline and Its N-Substituted Derivatives

Resumo

Abstract—Hybrid polymer nanomaterials are synthesized based on polyaniline (PAni) and its N-substituted derivative poly-3,6-dianiline-2,5-dichloro-1,4-benzoquinone (PDADCB) in combination with graphene oxide (GO). The electrochemical properties of electrodes formed by a composite polymer coatings based on PAni or PDADCB (combined with GO) and supported by glassy carbon and activated graphite foil (AGF) are studied. It is shown that the electron-conducting nanocomposite structure formed on the AGF foil has the electrochemical capacitance higher than 100 F/g and exhibits stable capacitance characteristics in a substantially extended potential interval in a protonic (1 М H₂SO₄) electrolyte.
