Abstract

Abstract: By means of FTIR, X-ray diffraction, TGA and DSC measurements, the structure of chitosan-fibroin blend membrane has been analyzed. The results showed that there was a strong hydrogen bond interaction between chitosan and fibroin in the blend membrane. Therefore, according to the result of X-ray diffraction as well as the phenomenon that the membrane was transparent and there was no obvious macrophase separation observed by SEM, it could be concluded that the chitosan-fibroin blend membrane was basically compatible. It was also found that the water adsorption property and the mechanical property of fibroin membrane were improved by blending chitosan.
