Electrochemical synthesis and characterization of poly (3,4-ethylenedioxythiophene)/electrochemically reduced graphene oxide (PEDOT/ERGO), prussian blue/ electrochemically reduced graphene oxide (PB/ERGO) and PEDOT/PB/ERGO electrodes

PEDOT has attracted a great deal of attention due to its suitable of band-gap energy range among the conducting polymers and the ease of operation in an aqueous solution. PEDOT film was deposited on the Au electrode surface using the electrochemical deposition technique. The PEDOT-ERGO layered composite was synthesis by sequential elektrodepozition of ERGO and PEDOT. In addition, ERGO/PB layered composite were syhtensized by electrodepozition of Prussian blue on the surface of ERGO. After it were determined that deposition conditions of the binary composite structures, the electrochemical synthesis of the PEDOT/ERGO/PM triple composite was performed. XPS, EDS and SEM techniques were used for the characterization of the composite film. It was determined that each material showed its own characteristic peaks in the composite material during the characterization process. These results indicate that the PEDOT/ERGO/PM layered composite is successfully synthesized by electrochemical deposition.
