MANUFACTURING METHOD OF ACTIVATED CARBON FIBER HAVING LARGE SPECIFIC SURFACE AREA AND HAVING NANO PORES FORMED BY CARBONIZING NANO FIBER MANUFACTURED BY ELECTRIC SPINNING METHOD

摘要

PURPOSE: A manufacturing method of activated carbon fiber is characterized by carbonizing nano fiber non-woven fabric without activating to form countless pores on a surface of the fiber. The activated carbon fiber has a large specific surface area. The activated carbon fiber is useful for electrode material, raw material of a catalyst carrier and high functional absorptive material. CONSTITUTION: Activated carbon fiber is obtained by the steps of: mixing precursor material of carbon fiber, inorganic compound and a solvent to manufacture a spinning solution; electric-spinning the spinning solution to manufacture nano fiber composited inorganic sa heating the composited nano fiber in air at 0.5-5deg.C/min. of heating velocity to 250-350deg.C, followed by maintaining the nano fiber at the final temperature for 0.1-3hours to oxidization-stabilize the fiber; and then carbonizing the fiber at 500-1500deg.C under an inert condition or under a vacuum condition.
