▎ 摘　　要

NOVELTY - Preparing carbon nanotube-graphene complex conductive fiber comprises warping the fibrous silk, adjusting the tension, sizing with carbon nanotube-graphene conductive dye, adjusting the amount of scraping, drying and winding, where the carbon nanotube-graphene conductive dye comprises 6.5-9 wt.% carbon nanotube, 0.5-1.5 wt.% graphene, 3-10 wt.% adhesive, 0.5-1.5 wt.% anionic dispersant, 0.05-0.1 wt.% defoamer, and deionized water (remaining amount). USE - The method is useful for preparing carbon nanotube-graphene complex conductive fiber. ADVANTAGE - The method: is low-carbon and environmental friendly; saves energy; reduces emissions; adjusts the sizing amount of fiber precursors by adjusting the viscosity of carbon nanotubes and graphene conductive dyes and the spacing of the squeegee; and dyes the ordinary fibers to obtain carbon nanotubes and graphene conductive fibers with surface resistance between 10-104 Ω/cm with different specifications and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the carbon nanotube-graphene complex conductive fiber prepared by the method.
