WAXD and FTIR results confirmed that the crystal structure of SF was not influenced by adding the different contents of SA, exhibiting the random coil structure in the hybrid scaffolds.
Conformational transition of SF from random coil to [beta]-sheet form can perform by heat treatment, alcohol treatment, polymer blending and cross-linking [7-9].
