摘要: Degummed Antheraeapernyi silk fibroin (APSF) fibers were dissolved in a lithium thiocyanate solution that was dialyzed against distilled water for 3 days. Solution-cast APSF films hexafluoroisopropanol to prepare spinning solution. Wet employed filaments. Scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, Raman solid-state 13C cross-polarization/magic angle nuclear magnetic resonance, and differential scanning calorimetry study the regenerated The results showed uniform distribution of molecular weights, largest one may have been greater than 200 kDa. filaments contained β-sheet, α-helix, random-coil conformations, their breaking strength 52.20% native fibers. © 2009 Wiley Periodicals, Inc.
