FTIR spectra data were collected from pure FC and SA; FC/SA
blend; fabricated FCA and FCA/COSs scaffolds to determine the
functional groups of pure materials, modifications and changes
in the functional groups of synthesized composite scaffolds after
chemical cross-links. The spectra were measured at a resolution of
4 cm−1 in the frequency range of 4000–500 cm−1 at room temperature
using (FTIR–Perkin–Elmer Spectrum, GX Washington DC, USA)
spectroscopy.
