▎ 摘　　要

NOVELTY - Continuous preparation of graphene hollow fiber involves continuously pulling out copper wire, immersing in an graphene oxide electrolyte, coating graphene on the copper wire surface in a electrochemical three-electrode system, continuously collecting copper wires coated with graphene, rolling, immersing the resultant product in an aqueous solution of ferric chloride to dissolve the copper wire, cleaning and drying. USE - Continuous preparation of graphene hollow fiber used in energy, sensing and braking applications of building foundation. ADVANTAGE - The method enables continuous preparation of graphene hollow fiber by controlling thickness and diameter. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for graphene hollow fiber.
