▎ 摘　　要

NOVELTY - Use of filament fiber of graphene modified material, is claimed. The filament fiber comprises ultra-fine metal mesh layer and a graphene fiber, the ultrafine metal mesh layer is woven into a mesh by an ultrafine metal wire, and the ultrafine metal mesh layer is coated on the outside of the graphene fiber. USE - Used as filament fiber of graphene modified material. ADVANTAGE - The filament fiber can improves the mechanical strength of the graphene fiber; has good effect of promoting a certain degree to improve the conductivity, stability and obvious beneficial effect.
