▎ 摘　　要

NOVELTY - Preparing conductive fiber involves preparing graphene derivative solution, coating the graphene derivative solution on the surface of the selected polymeric fiber to form a composite fiber, allowing the composite fiber to move at the set speed through the microwave heating zone in the set atmosphere, subjecting surface of graphene derivative layer to a heating process for short time, cooling the composite fiber, and then performing extrusion treatment to obtain the conductive polymer fiber with good conductive ability. USE - Method for preparing conductive fiber (claimed). ADVANTAGE - The method enables to prepare conductive fiber having excellent conductive performance, and is suitable for further development and application of conductive fiber and graphene material.
