▎ 摘　　要

NOVELTY - Preparing graphene containing conductive anti-bacterial composite fiber comprises (i) using dopamine hydrochloride, oxidation, graphene containing carboxy and nano-silver to process polyamide master batch, and obtaining functional master batch, mixing the functional master batch with the blank master batch, extruding and granulating the double-screw, melting and spinning. USE - The method is useful for preparing graphene containing conductive anti-bacterial composite fiber used in protective clothes, mask and surgical clothes. ADVANTAGE - The fiber has good anti-bacterial, good conductivity and tensile property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: 1. graphene containing conductive anti-bacterial composite fiber; and 2. use method of graphene containing conductive anti-bacterial composite fiber.
