▎ 摘 要
NOVELTY - A graphene fiber is a composite fiber of a metallic nanowire-doped graphene fiber. The composite fiber comprises 0.1-50 %mass metallic nanowires. The graphene is in sheet morphology. The metallic nanowires and the graphene sheets are arranged in parallel along the axial direction of the graphene fiber at the same time. USE - Graphene fiber is used for lightweight flexible lead wire. ADVANTAGE - The graphene fiber has high performance, excellent conductivity, tensile strength and toughness. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of the graphene fiber.
