▎ 摘　　要

NOVELTY - Graphene composite polyacrylonitrile (PAN) fiber comprises 10-35 pts. wt. graphene composite PAN masterbatch, 70-90 pts. wt. PAN, and 3-5 pts. wt. zwitterionic surfactant. The graphene composite PAN masterbatch comprises 30-50 pts. wt. graphene, 20-60 pts. wt. polyurethane, 5-15 pts. wt. conductive metal powder, 5-15 pts. wt. anionic surfactant, and 30-50 pts. wt. solvent. USE - Graphene composite PAN fiber. ADVANTAGE - The fiber has simple preparation, compact structure, and good conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene composite PAN fiber comprising melting PAN, mixing with graphene composite PAN masterbatch, adding zwitterionic surfactant, stirring in one direction to obtain mixed melt, and spraying mixed solution by spraying gun.
