The invention discloses a degradable high-molecular drug-loading fibrous membrane used for repairing scars. According to the invention, 0.01 to 5 parts of a scar repairing medicine by net weight are dissolved and dispersed in 100 parts of a biodegradable high-molecular material solution by weight, such that a mixed system is obtained. The mixed system is transferred into a spray liquid storing device. Through the altering of electrostatic spinning parameters, a haphazardly or directionally arranged target fibrous membrane is obtained. The electrostatic spun membrane provided by the invention has high porosity and good permeability, such that side-effects caused by poor permeability of a sealed membrane can be solved. The substrate material of the membrane is degradable high molecules. According to the invention, the medicine is sealed in the fibers, such that the stability of the structure of the medicine can be ensured; also, the medicine can be slowly released under the controlling of the degradation of the high-molecular material, such that the effect duration of the medicine is longer than that of traditional scar-repairing preparations or ointments. Further, the membrane can be cut into any required shape according to the dimension of a scar. Therefore, the membrane is easy to be customized and utilized.
