Left: DSC thermograms of samples Collagen-Phl.5 (—), Collagen-EDC60 (—) and type I collagen (—) obtained with 10 °C·min-1 heating rate. An additional thermogram of sample Collagen-Ph1 was acquired with 1°C·min-1 heating rate (—). All samples describe a triple helix denaturation by an endothermic transition at 67-88 °C. Right: ATR-FTIR spectrum of sample Collagen-Phl following DSC analysis; the main peaks of collagen can still be observed in the spectrum.
