摘要
A new method of preparing silk fibroin （SF） solution used in the decterospinning was introduced in this paper. According to the method, SF was dissolved in the LiBr/CH2O2 solution directly at room temperature. The method was compared with the traditional method--SF was dissolved in CaCl2 ternary solution. The structure of SF films and the morphology of SF nanofibers were examined by attenuated total reflectance fourier transform intrared （ATR- FTIR） spectroscopy, Scanning electron microscope （SEM） and optical polarizing microscope. The result of this study shows that the new method is a faster, more convenient and high cfficieat way to get the SF solution and the characteristics of SF fiber made by the new metbod is much better.
