▎ 摘  要

NOVELTY - High-strength flexible graphene fiber is claimed. The graphene fiber is prepared from graphene oxide and sodium alginate raw materials by wet fiber orientation technology and then dry winding. USE - The high-strength flexible graphene fiber is useful in signal transmission, energy storage and physiological information collection. ADVANTAGE - The high-strength flexible graphene fiber: solves the problems that the surface of the graphene fiber produced by wet spinning is rough, large number of defects and holes inside, orientation degree of the graphene layer is not high and the force between the layers is weak in the existing technology; has high-strength and flexibility; has improved electrical and mechanical properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of high-strength flexible graphene fiber. The method uses hydroiodic acid and ethanol. The method utilizes coagulation bath.
