    摘要: Disclosed is a method for fabrication of porous carbon fibers. More particularly, the method for fabrication of porous carbon fibers comprises the steps of: processing starch to prepare a gelled starch solution; adding organic acid to the gelled starch solution to prepare a starch solution; dissolving carbon nanotubes in a solvent and adding fiber formable polymer thereto to prepare a carbon nanotube/fiber formable polymer solution; mixing the starch solution with the carbon nanotube/fiber formable polymer solution obtained from the above steps, in order to prepare a carbon nanotube/starch/fiber formable polymer solution; electro-spinning or wet-state spinning the prepared carbon nanotube/starch/fiber formable polymer solution to produce starch composite fibers; oxidation heating the starch composite fibers, then, executing carbonization and vacuum heat treatment of the heated fibers, so as to fabricate the porous carbon fibers. The fabricated porous carbon fiber has high specific surface area and high capacitance, thereby being favorably applicable in manufacturing electrodes for a super capacitor, fuel cell, etc.
