Preparation and supercapacitive performance of three-dimensional

Wangjian de


three-dimensional reduced graphene oxide (RGO)/polyaniline (PANI) composite has been prepared in a single step bYthe ultrasonic irradiation OFA suspension ofgraphite oxide and gels using a PANI method.Scanning electronic microscopy (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD), Fourier transform INfrared Spectra (FT-ir), X-ray photoelectron spectra (XPS), and electrochemical measurements were to performedThe morphology, structure, and supercapacitive performance of the composite.The result showed this composite maintained the basic morphology of RGO, and that's PANI was inlayed insideNetwork.An outstanding supercapacitive performance is obtained when the mass ratio ofgraphite oxide and PANI was 1:1.Furthermore, the capacities reached 758 and f*g_1at 0.5 and 30a*g_1, respectively.The retention rate is foundto is86%after1000 cyclesat
