This work deals with the preparation and characterisation of keratin/cellulose films prepared by coagulating polymers blends from cuprammonium solution. Films were obtained by blending keratin extracted from wool by m-bisulphite/urea solution and cellulose in several proportions. The molecular weight distributions of extracted and regenerated protein were studied by gel-electrophoresis (SDS-PAGE); the chemical structure and molecular conformation were investigated by FT-IR spectroscopy; the surface morphology of the films was observed by scanning electron microscopy (SEM).
