A FTIR spectra of collagen fibers before and after each treatment step. B Survey XPS spectra of different collagen fiber samples. C N 1s, D C 1s, and E O 1s high-resolution XPS spectra of Nano-CFN. F XRD patterns of CFN, PSG-CFN, and Nano-CFN. G The computed surface charge density of PSG. H Energy profiles for interactions of Zr species and the dipeptide compound. I DSC water melting and vaporization curves for different samples. J Tensile stress–strain curves and K thermal denaturation temperatures of collagen fibers before and after each treatment step.
