▎ 摘　　要

NOVELTY - Improving porosity of degradable fibrous membrane, comprises doping graphene oxide in degradable material, increasing conductivity of electrostatic spinning solution, reducing electric field tension in spinning process, reducing the diameter of the electrostatic spinning, and increasing the obtained fibrous membrane aperture ratio. USE - The method is useful for improving porosity of degradable fibrous membrane. ADVANTAGE - The membrane has large specific surface area and high porosity, and provides material base for development of substrate of new degradable medicine carrier.
