ABSTRACT:
Disclosed is a method of coating a permeable sheet with amphiphilic proteins, the method including the steps of: 1) providing a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having relatively low surface energies; 2) providing an aqueous solution containing amphiphilic proteins, the solution having a relatively high surface tension; and 3) contacting the solution containing amphiphilic proteins under shear stress conditions with the matrix of fibrous material so that at least a portion of the amphiphilic proteins are adsorbed onto at least some individual exposed surfaces. Also disclosed is a protein-coated permeable sheet composed of: 1) a permeable sheet having a plurality of individual exposed surfaces, at least a portion of which having relatively low surface energies; and 2) amphiphilic proteins adsorbed onto at least some individual exposed surfaces to define a gradient distribution of amphiphilic protein coating along at least one dimension of the permeable sheet.
