NOVELTY - Polybutylene carbonate, polylactic acid and graphene are dissolved in solvent. A modified component is added to mixture and stirred, to obtain electrospinning liquid. The electrospinning solution is heated at 50-60 degrees C for 2-4 hours and subjected to electrospinning at 50-60 degrees C, electrospinning voltage of 15-20 kV, spinning speed of 0.1-1.5 mL/hour and aluminum foil distance of 15-20 cm for 2-10 hours using spinning spinneret, to obtain degradable graphene composite electrospun fiber membrane. USE - Preparation of degradable graphene composite electrospun fiber membrane (claimed). ADVANTAGE - The method enables preparation of degradable graphene composite electrospun fiber membrane with excellent mechanical property. DETAILED DESCRIPTION - Polybutylene carbonate, polylactic acid and graphene are dissolved in solvent. A modified component is added to mixture and stirred at 320-640 rpm for 90-120 minutes, to obtain electrospinning liquid. The volume ratio of graphene and solvent is 0.005-0.04 g:10 mL. The mass ratio of graphene and polybutylene carbonate is 1:10-80. The mass ratio of graphene and polylactic acid is 1:50-400. The mass ratio of modified component and polybutylene carbonate is 0-5:100. The electrospinning solution is heated at 50-60 degrees C for 2-4 hours and subjected to electrospinning at 50-60 degrees C, electrospinning voltage of 15-20 kV, spinning speed of 0.1-1.5 mL/hour and aluminum foil distance of 15-20 cm for 2-10 hours using spinning spinneret, to obtain degradable graphene composite electrospun fiber membrane.
