In this work, the fabrication and characterization of polyacrylonitrile (PAN)based porous caron fibers is investigated. The mesoporous carbon fibers were prepared by electrospinning and template technique. The diameter distributions of porous carbon fibers were indicated in the range of 250 to 480 nm and surface became rough. The specific surface area and total pore volume increased with an increase the silica content. Elevating the volume fraction of mesopores gave maximum specific capacitance, which could be explained on the basis of ion mobility in the pores. Thus, the capacitance of the electrodes was strongly dependent on the specific surface area and pore volumes of the fibers. |
