## Abstract The conformational transition of molecular chains of regenerated silk fibroin (SF) aqueous solution is systematically investigated by circular dichroism, Raman, IR, and UVβvis spectroscopies. It is found that an initial random coil conformation of the SF can be readily changed into an o

The conformation of silk fibroin in silk fibroin/chitosan (SF/CS) blend membrane was analyzed by infrared spectrum, X-ray diffractometry, and Raman spectrum. The results demonstrated that the SF could show b-sheet conformation when the SF content in blend membranes was 10% (w/w) and 60-80% (w/w), wh
A novel natural polymer blend membrane, namely chitosan/silk fibroin blend membrane, was prepared. The selective solubility and the pervaporation properties of alcohol-water mixture were studied. The results showed that the membrane was water selective and the separation factor of ethanol-water mixt
