| titleOfInvention | Composite barrier film and preparation method therefor |
| abstract | Disclosed is a composite barrier film, comprising an inner film (1) and an outer film (3), wherein the inner film (1) is a first electrospun film, the outer film (3) comprises a second electrospun film (4) and a casting film (2), the second electrospun film (4) is placed in a treatment solution to form the casting film (2), the material of the first or second electrospun film (4) comprises silk fibroin and/or a biocompatible polymer, and the material of the casting film (2) is silk fibroin. The preparation method for the composite barrier film involves: dissolving degummed silk fibroin and a biocompatible polymer in an organic solvent to obtain an electrostatic spinning solution, and then subjecting same to electrostatic spinning to obtain the first or second electrospun film (4); placing the second electrospun film (4) into a treatment solution, and forming a film by means of a casting method to obtain the outer film (3), wherein the treatment solution is an aqueous silk fibroin solution; and using the first electrospun film as the inner film (1), and compounding the outer film (3) and the inner film (1) to obtain the composite barrier film. |
