Abstract In this paper, the gelatin/PVA biodegradable composite films were prepared with gelatin(Gel) and poly(vinyl alcohol)(PVA) by a solvent casting method, which were modified by cross-linking with glyoxal. The chemical structure of the Gel/PVA composite films before and after glyoxal cross linking was characterized by Fourier Transform Infrared Spectroscopy(FTIR), X-ray diffraction(XRD), differential scanning calorimetr (DSC), and thermogravimetry analysis(TG). The effects of crosslinking agent concentration on mechanical properties and solubility the Gel/PVA composite films were investigated. The results show that with increasing the amount of glyxoal, the tensile strength of the Gel/PVA composite films increased and then decreased, while the elongation at break and solubility of the composite films decreased gradually. The melting temperature and thermal stability of the Gel/PVA composite films were improved by glyoxal crosslinking. The glyxoal crosslinking has an obvious effect on the hydrogen bonding between molecules and chemical structure of Gel/PVA composite films.
