▎ 摘  要

NOVELTY - The method for dry-wet spinning of oxidized graphene, involves preparing graphene oxide by modified Hummers method, washing, preparing graphene oxide spinning solution, extruding from the spinning capillary, solidifying colloidal layer into fiber, after the air enters into coagulation bath, drying and carrying out reduction reaction to obtain graphene fibers. USE - Method for dry-wet spinning of oxidized graphene (claimed). ADVANTAGE - The method eliminates the screening process of the graphene sheet, increases the draw ratio of fiber, improves the orientation of sheet in the fiber and improves fiber strength.
