Abstract Regenerated Antheraea pernyi (A. pernyi) silk fibroin porous material was prepared by freeze-drying. By means of X-ray diffraction, Fourier transform infrared spectrometry, 13C NMR and Raman spectroscopy, the molecular conformation of A. pernyi silk fibroin porous materials prepared under different freezing temperatures and different concentrations of silk fibroin solution were investigated and analyzed. The results indicated that the molecular conformation of silk fibroin inside regenerated Antheraea pernyi silk fibroin porous materials prepared by freeze-drying was due to the coexistence of α-helix and random coil structure, which was different from that of Antheraea pernyi silk fibroin fibers. The content of α-helix structure of freeze-dried material prepared under higher temperature had a tendency to increase. Crosslinking by PEG-DE can promote the transformation of silk fibroin from random coil to α-helix structure.
