The crystallization, exothermic, and electrochemical properties of coaltar pitch-based carbon fibers (CFs) with various temperatures were studied. The CFs were prepared from stabilized pitch-based carbon fiber at 500℃, 700℃, 900℃, and 1100℃ with 60 min. The surface and structural properties of the ACF were determined by scanning electron microscope (SEM) and X-ray diffraction (XRD), respectively. N2 adsorption isotherms at 77K were investigated by BET and BJH methods to characterize specific surface areas and pore volumes. The electrical conductivity was obtained by measuring the surface resistance with four probe method. |
