Mimetics of eggshell membrane protein fibers have been obtained with an electrospinning technique based on soluble eggshell membrane protein (SEP) prepared previously. Poly(ethylene oxide), a biocompatible and water soluble polymer, is used to improve the processability of SEP. Blends of SEP/PEO aqueous solutions were electrospun. The diameters of the fibers are 0.3-20 mum depending on the concentration of the solution and the proportion of SEP/PEO. Two "cross-linking" methods are investigated in order to improve the anti-water property of the fibers.
