Electrochemical supercapacitors are extensively studied as auxiliary energy storage devices in addition to rechargeable lithium ion batteries. In this study, we have fabricated a series of hybrid carbon nanofibers (CNFs) based on sulfonated poly(1,3,4-oxadiazole) (sPOD) and manganese dioxide (MnO2) for the self-standing supercapacitor electrode applications. For the purpose, hybrid precursor nanofibers are manufactured by electrospinning of sPOD solutions including different MnO2 nanoparticle contents and they are then carbonized at 1000 °C. XRD, FT-IR, EDS and Raman data are obtained to identify the microstructures of the hybrid CNFs. The morphological features of the hybrid CNFs are characterized by using SEM and TEM images. The electrochemical properties of sPOD/MnO2–based hybrid CNFs as self-standing supercapacitor electrodes are investigated by obtaining electrical conductivity, cyclic voltammetric and charge/discharge curves. |
