▎ 摘　　要

NOVELTY - Conductive fiber comprises a fiber main body, and a hollow part provided in the middle of the main fiber body, where the hollow part is filled with conductive material, and the conductive material comprises graphene, and is arranged in the hollow part in a grid manner in a tiled manner. USE - The conductive fiber is useful in a conductive type metal composite fiber by metal material and melt polymer method which is mixed with conductive metal medium polymer. ADVANTAGE - The conductive fiber has reduced conductive material dosage and improved conductive performance. The device cost is low, the occupied space is small, and it is easy to control. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the conductive fiber.
