▎ 摘　　要

NOVELTY - Producing conductive fiber, comprises (a) scouring a natural fiber silk, and (b) immersing the scoured silk in an aqueous solution containing graphene oxide to coat the surface of the scoured silk with graphene oxide, where the scouring and coating steps are carried out continuously. USE - The method is useful for producing conductive fiber. ADVANTAGE - The method performs without separate adhesion medium or fiber surface modification process, produces conductive fiber having excellent conductivity by coating on natural fiber without separate bonding agent or surface modification process of the fiber, and adequate flexibility and strength, is economical, utilizes silk having pyroprotein property as natural fiber, and improves conductivity without denaturation of the fibers through simple thermal reduction.
