Abstract: By sequentially performing: a step (I) of dissolving fullerene C60 in a polyalkylene glycol to prepare a fullerene solution; a step (II) of immersing a material carbon fiber in the fullerene solution; and a step (III) of extracting the carbon fiber from the fullerene solution, washing the extracted carbon fiber with water, and drying the carbon fiber washed with water, a carbon fiber on which fullerene C60 adsorbs is obtained.

Abstract: By sequentially performing: a step (I) of dissolving fullerene C70 in an organic solvent to prepare a fullerene solution; a step (II) of immersing a material carbon fiber in the fullerene solution; and a step (III) of extracting the carbon fiber from the fullerene solution and drying the extracted carbon fiber, a carbon fiber on which fullerene C70 adsorbs is obtained.

Abstract: A carbon fiber is obtained by sequentially performing: a step (I) of dissolving a fullerene mixture including fullerenes C60 and C70 in an organic solvent to prepare a fullerene solution; a step (II) of immersing a material carbon fiber in the fullerene solution; and a step (III) of extracting the carbon fiber from the fullerene solution and drying the extracted carbon fiber.
