▎ 摘　　要

NOVELTY - Preparing graphene-based conductive fiber involves using organic solvent, lye and water on the surface of high molecular fiber at room temperature, washing to remove chemical surface oil stain and impurity, and then drying. The certain amount of graphene or graphene/carbon nano-tube mixed powder is placed in mixed solvent for mechanical stirring and ultrasonic dispersion to obtain conductive dispersion. The conductive dispersion is coated on the high molecular fiber, washed by on-line water washing and then dried to obtain graphene-based conductive fiber. USE - Method for preparing graphene-based conductive fiber (claimed). ADVANTAGE - The method enables to prepare graphene-based conductive fiber that has high conductivity and good performance.
