An electrospun nanofiber membrane and a method for preparing the electrospun nanofiber membrane are provided to solve problems of poor mechanical properties, short service life, poor uniformity and consistency of orientation of fibers and poor stability of fiber networks in current electrospun composite nanofiber materials. The electrospun nanofiber membrane is prepared by spinning solution through a high-voltage electrospinning device. The spinning solution is blending solution of regenerated silk fibroin: polyvinyl alcohol: polylactic acid with a mass ratio being 75-85:10-20:5 dissolved in a mixed solvent of trifluoroacetic acid and dichloromethane with a volume ratio being 7:3. The method establishes a reasonable mass ratio parameter of the regenerated silk fibroin, the polyvinyl alcohol and the polylactic acid to blending spinning to improve spinnability of silk fibroin, as well as prepare the electrospun composite nanofiber membrane with good mechanical properties.
