초록

Surface properties of carbon nanofibers (CNFs) were modified by electron beam (e-beam) irradiation, andelectrochemical performances of treated CNFs as the supercapacitor electrode were investigated. Since the capacity ofa supercapacitor is affected by the surface properties of the electrode, the improvement of the electrode surface propertiesusing various techniques has been widely investigated, however, e-beam treatment on CNFs is quite limited. In this study,CNFs were manufactured through the carbonization process of polymer nanofibers fabricated using electrospinning, andstructural and electrochemical properties of e-beam irradiated CNF electrodes were analyzed. By the e-beam treatment,the diameter of CNF decreased from 646 nm to 457 nm, and the surface area increased from 529 m2g-1 to 1452 m2g-1.
e-Beam irradiated CNFs were used as supercapacitor electrodes to analyze their electrochemical performance and showeda great electrochemical performance compared to the pristine CNFs.
