Study on Improving Biodegradation Process of Regenerated Silk Fibroin Fiber
The native silk fibroin fiber from Bombyx mori has been used as suture with non-degradable character. Therefore, preparing biodegradable silk fibroin fiber is very attractive and important. In this paper, the biodegradable silk fibroin fiber with high strength was prepared according to the process of regenerated silk fibroin fiber from the 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) solution and by adding calcium chloride CaCl2 to the silk fibroin solution. The degradation rate of the regenerated silk fibroin fibers was dependent on calcium chloride concentration.
