▎ 摘  要

NOVELTY - Manufacture of chitosan-graphene oxide/polyacrylonitrile double-layered nanofiber membrane involves soaking graphene oxide in N,N-dimethylformamide, ultrasonically processing at room temperature for 60-120 minutes to obtain uniform graphene oxide dispersion, adding polyacrylonitrile, stirring at room temperature for 5-10 hours, preparing graphene oxide/polyacrylonitrile nanofiber membrane by electrospinning using graphene oxide/polyacrylonitrile electrospinning solution, and drying. USE - Manufacture of chitosan-graphene oxide/polyacrylonitrile double-layered nanofiber membrane. ADVANTAGE - The method enables simple manufacture of chitosan-graphene oxide/polyacrylonitrile double-layered nanofiber membrane with improved mechanical properties, tensile strength and elastic modulus.
