▎ 摘  要

NOVELTY - A graphene oxide/sodium polyacrylate composite spinning fluid is obtained by preparing an aqueous solution (s1) of sodium polyacrylate having a concentration of 0.2% or more, and an aqueous solution (s2) of graphene oxide having a concentration of 0.2% or more, and mixing solutions (s1) and (s2) at a mass ratio of 3 times or more. The weight average molecular weight of sodium polyacrylate is 30000000. USE - Graphene oxide/sodium polyacrylate composite spinning fluid is used for preparing graphene fabric (claimed). ADVANTAGE - The graphene oxide/sodium polyacrylate composite spinning fluid has excellent workability, and enables simple and environmentally-friendly preparation of graphene fabric having excellent tensile strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for usage method (M1) of graphene oxide/sodium polyacrylate composite spinning fluid for preparing graphene fabric, which involves subjecting the composite spinning fluid as precursor to air-assisted spinning, drying, and forming nonwoven fabric.
