Fig. 2. (A) FT-IR Spectra of PG11, PG12, PG14 with characteristic peaks representing the particular functional groups corresponding to parental Gelatin and PVP. (B) Thermal degradation of both components present in the scaffolds was shown in their TGA thermograms. (C) Derivative Thermal Analysis (DTA) of pure gelatin, pure PVP, PG11 and PG14 confirming the stability and the degradability of the scaffolds. This shows the interaction of the polymers after cross linking. (D) Swelling profile of PG11, PG12 and PG14 over a period of 30 days reveals the stable swelling property and the ability to support the regeneration of tissues.
