PREPARATION METHOD OF CARBON NANO-FIBER USING ELECTROSPINNING

摘要

PURPOSE: A method for fabricating carbon nanofiber by electrospinning is provided to easily produce carbon nanofiber with C shape or hollow cross-section. CONSTITUTION: A method for fabricating carbon nanofiber by electrospinning comprises: a step of preparing a first polymer solution and a second polymer solution; a step of electrospinning the first and second polymer solutions simultaneously to prepare a core-shell type composite fiber; a step of performing thermal treatment of the composite fiber to stabilizing polyacrylonitrile of the core-shell composite fiber; and a step of carbonizing the polyacrylonitrile and burning. The first polymer solution is prepared by melting polyacrylonitril in a first solvent. The second polymer solution is prepared by dissolving acrylonitrile-containing copolymers in a second solvent.
