PREPARATION METHOD OF CARBON NANOFIBER USING RADIADION, AND THE CARBON NANOFIBER THEREBY

摘要

PURPOSE: A method for fabricating a carbon nanofiber by radiation is provided to perform fiber stabilization through radiation and to obtain the carbon nanofiber with improved strength. CONSTITUTION: A method for fabricating a carbon nanofiber by radiation comprises: a step of dissolving hydrocarbon-based polymers in a solvent and electrospinning to prepare fibers; a step of irradiating the fiber by radiation and stabilizing the fibers; and a step of carbonizing the fiber. The hydrocarbon-based polymers contain polyacrylonitrile, lignin, rayon, pitch-based polymers, phenol-based polymers, polyethylene, or polyvinyl alcohol.
