Electropolymerization of graphene oxide/polyaniline composite for high-performance supercapacitor

---

Abstract.
The graphene oxide/polyaniline (GO/PANI) composite was prepared by the one-step electrochemical codeposition
method. The different mass concentrations of GO were utilized to improve the electrochemical
performances. Scanning electron microscope and transmission electron microscope images showed that
PANI nanofibers not only were coated on the surface but also intercalated into GO sheets. The maximum
specific capacitance of the GO/PANI composite achieved 1136.4 F g−1 with a GO concentration of
10 mg L−1 at a scan rate of 1 mV s−1, which is almost two-fold higher than that of PANI (484.5 F g−1). The
GO/PANI composite also showed a good cycling stability, retaining over 89% of its initial capacitance
after 1000 cycles. High electrochemical performances were attributed to increasing active sites for the
deposition of PANI provided by large surface areas of GO sheets and the synergistic effect between GO
and PANI, shortening the ion diffusion paths. Results indicate that the GO/PANI composites can be developed
as excellent electrode materials of high-performance supercapacitor by a versatile, effective and
environment-friendly method.
