▎ 摘　　要

NOVELTY - The process comprises supplying a spin-dope comprising graphene ribbons to a spinneret, spinning the spin-dope into accrued graphene ribbon fibers, coagulating the accrued graphene ribbon fibers in a coagulation medium to form coagulated graphene ribbon fibers, stripping, optionally neutralizing and washing the coagulated graphene ribbon fibers, and winding the coagulated graphene ribbon fibers. The spin-dope is formed by dissolving the graphene ribbons in a solvent. The coagulation medium flows in the same direction as the accrued graphene ribbon fibers. USE - The process is useful for spinning graphene ribbons into fibers to manufacture graphene ribbon fibers (claimed), which are useful in yarns, nonwovens, membranes and films. ADVANTAGE - The process is capable of accurately spinning the graphene ribbons into fibers thus providing the graphene ribbon fibers with improved performance, excellent flexibility and high strength. DETAILED DESCRIPTION - The process comprises supplying a spin-dope comprising graphene ribbons to a spinneret, spinning the spin-dope into accrued graphene ribbon fibers, coagulating the accrued graphene ribbon fibers in a coagulation medium to form coagulated graphene ribbon fibers, stripping, optionally neutralizing and washing the coagulated graphene ribbon fibers, and winding the coagulated graphene ribbon fibers. The spin-dope is formed by dissolving the graphene ribbons in a solvent. The coagulation medium flows in the same direction as the accrued graphene ribbon fibers. The accrued graphene ribbon fibers and the coagulation medium are transported in a vertically upward direction, a horizontal direction and a vertically downward direction. The coagulation medium is sulfuric acid having a concentration of 90-100%. A temperature of a coagulation bath is 5 degrees C. The accrued graphene ribbon fibers are spun into the coagulation medium via an air gap. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a process for manufacturing graphene ribbon fibers.
