NOVELTY - Preparation of graphene yarn involves adding 4-7 mg/mL graphene dispersion and yarn-forming particles yarn in the weight ratio of 1:60 to twin-screw extruder for miscibility to obtain miscible substance, mixing graphene dispersion homogeneously into miscible material during heating process, mixing and extruding yarn material using twin-screw extruder and drawing yarn material using drawing machine. USE - Preparation of graphene yarn. ADVANTAGE - The graphene yarn prepared has excellent ductility and conductivity.
