项目摘要
Structural analyses of wet-heated silk fibroin materials were performed by solid-state 13C CP/MAS NMR and 13C PST/MAS NMR measurements. It was revealed that the wet-heating treatments changed secondary structures of silk fibroin molecules in fabrics and sponges. It is thought that different initial structures of silk fibroin materials induced the different interactions between fibroin molecules and water near the surface during the wet-heating treatments, and different interactions influenced structural changes and molecular mobility of silk fibroin molecules. In addition, it was found that contents of the unknown structure, which was assumed to be silk III, were changed by wet-heat treatments and water contents.
用固体13 C CP/MAS NMR和13 C PST/MAS NMR对湿热丝素材料进行了结构分析。结果表明,湿热处理改变了织物和海绵中丝素蛋白分子的二级结构。认为丝素材料的初始结构不同,导致湿热处理过程中丝素分子与表面附近水之间的相互作用不同,不同的相互作用影响丝素分子的结构变化和分子运动性。此外,发现了未知结构的含量,其被认为是丝III,通过湿热处理和水含量而改变。
