We report on the dissolution of semi-domestic silk type Antheraea assamensis using ionic liquids. We investigated the impact of different coagulating solvents, including isopropanol and water on the structure and the morphology of the regenerated silk. We found that the water regenerated silk film showed a high -sheet content and a native silk-like XRD pattern. (c) 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
