The invention provides a preparation method of an electrospinning collagen film. Collagen, acetic acid and water are mixed to obtain a spinning solution, and electrospinning is performed; wherein, the mass fraction of collagen is 9-10%, and the content of acetic acid is 9-10%. The quality score is 27‑37%. The invention also provides the prepared electrospinning collagen film and its use. The method of the invention is simple, convenient and environmentally friendly, and the prepared collagen membrane has good appearance, soft texture, high elastic modulus and strong mechanical properties, greatly broadens the application of collagen in tissue engineering and regenerative medicine, and has good clinical prospects . |
