▎ 摘  要

NOVELTY - Super stretch and high electric conduction graphite fiber comprises graphene sheet layers with double Archimedean spiral structure, 0.336 nm lamellar spacing, 57.87-96 fiber oxygen ratio, 26-26.5 degrees diffraction peak position, 0.8-2.36x 106 S/m conductivity and 30-220% breaking elongation rate. USE - Super stretch and high electric conduction graphite fiber. ADVANTAGE - The fiber has simple process and high conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphite fiber comprising preparing 0.5-5 mu m graphene oxide film; heating at 0.1-1 degrees C/minute to 500-800 degrees C, and keeping temperature for 0.5-2 hours; heating at 1-3 degrees C/minute to 1000-1300 degrees Cd, and keeping for 0.5-3 hours; heating at 5-8 degrees C/minute to 2000-3000 degrees C, and keeping temperature for 0.5-4 hours; and cutting into strips, connecting ends of strips, winding at 250-500 revolutions/minute for 1-5 minutes.
