Study on effect of N-containing polymer/graphene electrical-conducting composites for supercapacitor electrodes |
| 초록 |
A polypyrrole and reduced graphene oxide composite (PPy/rGO) was successfully synthesized via an in situ polymerization. The structure and morphology of the composite are characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometer (FTIR), scanning electron microscopy (SEM) and transmission electron microscope (TEM). Electrochemical properties were characterized by cyclic voltammetry (CV) in 1M NaNO3 electrolyte. The nanostructure of the PPy was induced and greatly affected by the addition of graphene during the synthesis process, which might greatly contribute to the electrochemical properties of the composite. The electrochemical tests show that the PPy/rGO composite exhibits the highest specific capacitance among investigated materials and excellent cycling stability. The composite is a promising candidate for supercapacitors to have higher specific capacitance and better rate capability than those of pure polypyrrole. |
