Electrochemical deposition and characterization of polyaniline-grafted graphene oxide on a glassy carbon electrode

Abstract

The synthesis and characterization of electrochemically deposited polyaniline-grafted graphene oxide was successfully carried out. Excellent electrochemical stability, thermal consistency, reversibility and lower internal resistance were noted at various current densities when graphene oxide was electrochemically deposited on the surface of conducting polyaniline at + 0.75 V. Electrochemical deposition of graphene oxide on the polyaniline was confirmed by scanning electron microscopy, Fourier transformed infrared spectroscopy, Raman scattering and UV/Vis spectroscopy measurements. The electrochemically deposited polyaniline-grafted graphene oxide is confirmed in various characterization techniques employed and has promising electrochemical features due to its good transparency and stability and hence can find various applications in the manufacture of electronic materials and in the construction of electrochemical sensors that are cheap, simple and environmental friendly.
