摘要
A method for manufacturing two-component carbon nanofibers and activated carbon nanofibers is provided to increase specific surface areas of the carbon nanofibers and improve electrical conductivity of the carbon nanofibers, and usefully apply the carbon nanofibers to electrode materials, adsorbing materials, and carbon fiber fillers for composite materials. A spinning solution is prepared by dissolving PAN(polyacrylonitrile) and pitch, as carbon fiber precursors, into an organic solvent solution selected from THF(tetrahydrofuran), DMF(dimethylformamide), DMAc(dimethylacetamide), pyridine, and quinoline. A high voltage is applied to the spinning solution to produce organic nanofibers having radii of 0.1-0.9um through electrospinning. The organic nanofibers are oxidation-stabilized to produce flameproof fibers using air. The flameproof fibers are carbonized, activated, or graphitized to produce carbon nanofibers, activated carbon nanofibers, or graphite carbon nanofibers.
