▎ 摘 要
NOVELTY - Graphene/carbon nanotubes (CNTs) composite fiber comprises graphene sheets stacked in the thickness direction of the fiber; and CNTs intercalated between the graphene sheets and extending along the londitudinal direction of the fiber, where the interval between the graphene sheets in the region where the CNTs are not sandwiched is 3.6-3.7 Angstrom . USE - Used as graphene/CNTs composite fiber. ADVANTAGE - The graphene/CNTs composite fiber has excellent mechanical strength, preferably tensile strength and torsional strength, excellent electrical properties, and good elasticity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for manufacturing graphene/CNTs composite fiber.
