With the advantage of two dimensional (2D) correlation FT-IR spectroscopy, the conformation transition of regenerated silk fibroin film was studied under thermal treatment. The results showed that the conformation changed when the film was heated from 130 to 220℃ as well as maintained at 180℃ for different time courses. It was also found that the conformation response order was random coil prior to β-sheet and α-helix.
