Preparation and Characterization of Gamma Radiation Cured Gelatin-PVA Bio-Blend

Article Preview

Abstract:

Gelatin-PVA blend films of different compositions (0%, 5%, 10%, 15% of PVA) were prepared by casting. The tensile strength (TS) and elongation at break (Eb) of the films were studied. The TS and Eb of pure gelatin films were found to be 32 MPa and 3.3% respectively. The films were irradiated under different gamma radiation dose (50 Krad, 100 Krad, 150 Krad, 250 Krad, 500 Krad). 5% PVA containing gelatin films irradiated under 100 Krad gamma radiation showed highest TS of 42 MPa and highest Eb of 4.2%. Thermal property of the films was studied by Thermomechanical analysis (TMA) and Thermogravimetric Analysis (TGA). The grafting of PVA onto gelatin is studied by IR. In order to study surface morphology SEM study was undertaken.
