In this study, silk fibroin webs were prepared by ultrasonication of degummed silk and electrospinning of regenerated silk fibroin, and their structural characteristics were examined. XRD and FTIR spectroscopy indicated that β-sheet crystalline was found in both silk fibroin webs. 2 theta peaks of silk webs were appeared at 9, 20, and 23o, respectively, regardless of preparation method. In case of FTIR measurement, β-sheet conformations were observed at amide I, II, and III bands for silk fibroin webs. Scanning electron microscopy result showed that several hundred nano meter fiber diameters with a relatively evenness were obtained by electrospinning of regenerated silk fibroin. |
