Mechanism of the Gelation of Fibroin Solution

Degummed silk was dissolved in a mixture of CaCl 2 and ethanol at low temperature. The concentration and pH of the centrifuged, filtered, and dialyzed silk solution were adjusted, and then it was kept in an air-conditioned room for gelation. The mechanism of the gelation and the gel structure were s...

Description
Summary:Degummed silk was dissolved in a mixture of CaCl 2 and ethanol at low temperature. The concentration and pH of the centrifuged, filtered, and dialyzed silk solution were adjusted, and then it was kept in an air-conditioned room for gelation. The mechanism of the gelation and the gel structure were studied. It was found that the gel was formed due to the formation of beta-structure in the fibroin solution. The gelation was dependent on the pH of the fibroin solution.
