▎ 摘　　要

NOVELTY - Production of graphene carbon black composite conductive fiber comprises mixing polyamide-based fiber-forming polymer and/or polyester-based fiber-forming polymer powder, graphene powder and carbon black powder to obtain conductive masterbatch, and spinning to obtain product. USE - Method for producing graphene carbon black composite conductive fiber. ADVANTAGE - The method has constant breaking strength and elongation of conventional carbon-doped powder and less than or equal to 103 ohms resistance characteristic.
