Bovine serum albumin-polycarbonate composite membrane and preparation method thereof

The invention discloses a bovine serum albumin-polycarbonate composite membrane and a preparation method thereof. The method comprises the steps of: orderly soaking commercial polycarbonate membranes into water-phase monomer bovine serum albumin and organic-phase monomer trimesoyl chloride, and preparing the bovine serum albumin composite membrane by interfacial polymerization. The bovine serum albumin-polycarbonate composite membrane has the advantages that the bovine serum albumin composite membrane is prepared by an interfacial polymerization method; and the composite membrane has pH and ion strength response performance, and has the characteristics of high flux, high selectivity and the like under ultra-low operation pressure.
