Res., 30, 223 2022 Gelatin/polyvinyl alcohol PVA g/P porous hydrogels containing different g/P ratios are prepared by chemical crosslinking, followed by physical crosslinking. The peaks at 1623 cm-1 and 1522 cm-1 corresponded to the formation of imine C=N , which came from the interaction between the amine groups of gelatin and the aldehyde groups of GA. The peak at 1086 cm-1 was attributed to the reaction of the al...
