Preparation method of composite material of silk fibroin and marine mussel adhesion protein

The invention relates to a preparation method of a composite material of silk fibroin and marine mussel adhesion protein, and discloses a preparation method of a multifunctional material composited by silk fibroin and marine mussel adhesion protein. The preparation method comprises the following steps: dissolving regenerated silk fibroin and a certain ratio of marine mussel adhesion protein in a certain amount of organic solvents, continuously stirring for well mixing so as to prepare a mixed solution of silk fibroin and marine mussel adhesion protein with a certain concentration, and preparing membranes or stents by a certain amount of the mixed solution. The whole treatment process of the preparation method of the invention has the advantages of low energy consumption, high biosecurity, low price, simple and convenient operation, no environment pollution and the like; Composite nanofiber membranes of biological fibroin and marine mussel adhesion protein prepared by the method of the invention has strong mechanical properties.
