▎ 摘　　要

NOVELTY - A high-strength continuous graphene fibers comprise graphene fibers orientated along axial direction with orientation degree of 70-80%, and having density of 1.3-2 g/cm3. USE - High-strength continuous graphene fibers used for preparing polymer composite used as reinforcing filler and knitted fabric used in electromagnetic shielding material and microwave-absorbing material. ADVANTAGE - The high-strength continuous graphene fibers have excellent mechanical property and electroconductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of high-strength continuous graphene fibers, which involves dispersing 1 pt. wt. oxidation graphene oxide in 10-100 pts. wt. solvent, processing for 10-60 minutes under vacuum degree of 0.001-0.1 Pa, obtaining graphene oxide spinning liquid, spinning at 1-100 mL/hour, processing in coagulating bath, obtaining graphene fibers, reducing using reducing agent, washing, drying and heat treating at 600-1300 degrees C in a tubular furnace.
