The regenerated wool keratin films were prepared from the wool keratin/ionic liquid solutions through water, methanol and ethanol as coagulation solvents in this article. It could be suggested from the results that [AMIM](+)center dot Cl- ionic liquid has higher solubility for wool keratin fibers than [BMIM](+)center dot Cl- ionic liquid. IR data showed the part of the disulfide bonds was broken during the dissolution. It could be seen from XRD data that the regenerated films exhibited a beta-sheet structure and the disappearance of the a-helix structure. TGA curves indicated that the thermal stability of regenerated wool keratin films decreased slightly compared to nature wool fibers. (C) 2012 Wiley Periodicals, Inc. J. Appl. Polym.
