摘要: 通过FTIR、X射线衍射、TGA和DSC等手段对壳聚糖-丝心蛋白合金膜的结构进行了表征.结果表明,合金膜中壳聚糖和丝心蛋白之间存在着较强的氢键相互作用,根据X射线衍射结果并结合合金膜表观均匀透明、扫描电镜观察未发现明显宏观相分离,认为合金膜是基本相容的.同时发现,在丝心蛋白中共混一定量的壳聚糖可以改善其吸水性和机械性能.

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.
