Reduced graphene oxide(RGO) was fabricated using gelatin as a reductant, and it could be stably dispersed in gelatin solution without aggregation. A series of RGO/gelatin composite films with various RGO contents were pre-pared by a solution-casting method. The structure and thermal properties of the RGO/gelatin composite films were char-acterized by UV-vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM),differential scanning calorimeter (DSC) and thermal gravi-metric analysis(TGA). scanning electron microscopy(SEM), differential scanning calorimeter(DSC) and thermal gravi-meteic analysis(TGA). The addition of RGD enhances the degree of crosslinking of gelatin films and decreases the swell-ing ability of the gelatin films in water, indicating that RGD/gelatin composite films have a better wet stability than gelatin films, The glass transition temperature(Tg)of gelatin films is also increased with the incorporation of RGO. The presence of RGO silms. Since gelatin is a natural and nontoxic biomacromolecule, the RGD/ gelatin composite films are expected to have potential applications in the biomedical field.
