Özet

Herewith, we report the development of a novel nanocomposite comprising strontium hexaferrite (SrFe12O19), reduced expanded graphene oxide, and polyaniline (SGP) for use as supercapacitor electrodes. The synthesized materials were systematically characterized using Fourier-transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy. SEM analysis confirmed the formation of graphene sheets with a uniform dispersion of SrFe12O19 particles within the composite. The incorporation of strontium hexaferrite into the composite significantly improved its electrochemical performance, resulting in an exceptional specific capacitance of 684 F g(-)1. Electrochemical comparisons of the individual and composite components revealed that the ternary SGP composite exhibited the highest specific capacitance. Galvanostatic charge-discharge measurements demonstrated excellent cyclic stability, with a retention rate of 98.96%. Furthermore, electrochemical impedance spectroscopy showed that the SGP composite had the lowest charge-transfer resistance, facilitating enhanced faradaic reactions. These findings highlight the potential of the SGP nanocomposite as an efficient electrode material for high-performance supercapacitor applications.
