Regenerated silk fibroin using protic ionic liquids solvents: towards an all-ionic-liquid process for producing silk with tunable properties

摘要

We have shown that protic ionic liquids, pILs, are effective coagulation solvents for the regenerated of silk fibroin, RSF. We show that the choice of pIL has a dramatic effect on the composition of the RSF. Additionally the use of pILs as the coagulator eliminates the need for volatile organic solvents in silk processing.
