NOVELTY - The method comprises preparing solution containing nematic content of 1-10 mg/ml and graphene oxide particle size of more than 10 mu m then carrying out electrostatic spinning to obtain nanofiber film or nanofiber membrane bundle. USE - The method is useful for producing carbon-based fiber (claimed). ADVANTAGE - The method is capable of producing carbon-based fiber in a simple manner with good electrostatic spinning property and without stretching effect.
