NOVELTY - Preparation of conductive graphene nanofiber film includes dissolving spinning material in mixed solution of tetrahydrofuran and N,N-dimethylformamide, stirring until the solution is clear, centrifuging to remove air bubbles, electrospinning into nanofiber, vacuum drying at room temperature to obtain electrospun nanofiber film, coating with graphene oxide dispersion liquid, drying, subjecting to reduction reaction, after the reaction is completed, washing with anhydrous ethanol, and naturally drying to obtain the product. USE - Preparation of conductive graphene nanofiber film. ADVANTAGE - The method is simple and provides conductive graphene nanofiber film with improved conductivity. DETAILED DESCRIPTION - Preparation of conductive graphene nanofiber film comprises dissolving spinning material in mixed solution of tetrahydrofuran and N,N-dimethylformamide, stirring until the solution is clear, centrifuging to remove air bubbles, electrospinning into nanofiber, vacuum drying at room temperature to obtain electrospun nanofiber film, preparing graphene oxide dispersion liquid by mechanically stripping graphene oxide using a machine and ultrasonically dispersing in ice water mixture liquid, filtering graphene oxide dispersion liquid, coating the electrospun nanofiber film with graphene oxide dispersion liquid at 1-3 ml/cm2, drying at 20-80 degrees C, subjecting to reduction reaction at 60-100 degrees C for 0.5-1.5 hours, after the reaction is completed, washing with anhydrous ethanol, and naturally drying to obtain the product.
