Abstract
A crosslinked protein-based separation membrane and application thereof. The separation membrane is formed by attaching a crosslinked protein nanomembrane to a porous membrane, the crosslinked protein nanomembrane is formed by crosslinking a two-dimensional nanomembrane which is formed by phase transition of a protein with a crosslinking agent, the separation membrane contains a dense surface layer and a support layer, the dense surface layer is the crosslinked protein nanomembrane, and the support layer is the porous membrane; the protein is any one of lysozyme, bovine serum albumin, insulin, and α-lactalbumin; the crosslinked protein-based separation membrane has a good biocompatibility, may serve as a dialysis membrane for blood purification, and has a higher retention ratio for large molecular proteins.
