▎ 摘　　要

NOVELTY - Manufacture of carbon macrotube (90) involves providing at least one layer of graphene, and wrapping at least one layer of graphene around scaffold material. USE - Manufacture of carbon macrotube. Uses include but are not limited to structural materials used in aerospace components, armor, high-tension support cables, wires and electrical conductors used in high voltage power transmission lines. ADVANTAGE - The method enables manufacture of carbon macrotube capable of providing lightweight electrical conductors having excellent electrical properties, and high tensile strength. A cable prepared using carbon macrotube is capable of supporting thin layered conductor/dielectric parallel and coaxial structures which transmit large data rates. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene sheet. Copper foil (22) Polymer sheet (56) Graphene (62) Scaffold tube (84) Carbon macrotube (90) Reel (92)
