▎ 摘　　要

NOVELTY - A graphene oxide fiber is manufactured by preparing a graphene oxide dispersion containing graphene oxide sheets and a dispersion medium; preparing a graphene oxide gel fiber (30a) by spinning the dispersion into a coagulation bath (200) containing a coagulating solvent which extracts the dispersion medium, a crosslinking agent which forms crosslinks between graphene oxide sheets and emulsifier for mixing the coagulating solvent and the crosslinking agent; and drying the graphene oxide gel fiber. USE - Manufacture of graphene oxide fiber. ADVANTAGE - The organic coagulation bath can control the shrinkage and drying speeds of graphene gel fiber during spinning in manufacture of a graphene oxide fiber using wet spinning. The manufactured graphene oxide fiber may exhibit excellent structural stability and facilitate hybridization with various materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for coagulation bath (200) for graphene wet spinning comprising a coagulating solvent which extracts a dispersion medium from a spun graphene oxide dispersion containing graphene oxide sheets and dispersion medium, a crosslinking agent which forms crosslinks between the graphene oxide sheets, and an emulsifier which mixes the coagulating solvent and the crosslinking agent. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the process of manufacturing a graphene oxide fiber using a coagulation bath.
