Figure.2 TG curve of the eri-silk
2.4 The analysis of infrared spectrum about the eri-silk
Figure.3 The infrared spectrum of the eri-silk
The Infrared spectral bands of silk fibroin protein contain 1660~1647cm-1 (amide I), 1546~1540cm-1 (amide II), 1330~1294 cm-1 (amideⅢ), 896~890 cm-1 (amide IV), 625~615 cm-1 (amide v) for α-helical structure;1640~1615cm-1 (amide I), 1535~1514cm-1 (amide II), 1245~1220cm-1 (amide Ⅲ), 965cm-1(amide IV), 700~696 cm-1 (amide V) for beta-folding structure, and 660~655cm-1 (amide V) for a random curl structure.The IR spectrum of eri-silk after degumming silk is shown in Fig.3, there contain α-helix and β-collapse structure in the structure of silk , dominated by β-collapse structures, and there is characteristic crest peak of amide I at 1661.
