A Novel Hydrophobic-Induced Method for Water Soluble Silk Fibroin

Abstract:

A new hydrophobic method of regenerated silk fibroin was introduced here, in which glycerol was used as the inducer. As a consequence, the soluble form of silk was transformed into hydrophobic form, which hence suggests glycerol has a significant effect of hydrophobic induction. Then the morphology and mechanical properties of the hydrophobic silk fibroin was respectively shown by scanning electron microscope (SEM) and strain test. The results showed induced silk fibroin had a compact surface and good mechanical property. Finally, the induction mechanism of glycerol was discussed that glycerol could soften the fibroin’s structure during dry process ,which was the main reason leading to β-sheets of fibroin partly being rebuilt and then the hydrophobic transformation being achieved.
