| Abstract: | The present work is an attempt to prepare biodegradable films of sodium alginate (SA)/polyethylene oxide (PEO) blend tailored by methacrylate (MA) and γ irradiation following casting method. The effects of SA/PEO composition, glycerol as a plasticizer, methacrylate as a monomer, and radiation dose were investigated and it was found that the mechanical properties of the films strongly depend on the film-forming parameters. The incorporation of glycerol in the blend is crucial as it creates a suitable environment for monomer addition and points out that tensile strength of the films decreased, while the elongation at break increased. Moreover, it was found that the tensile properties were improved by the application of γ radiation as well as monomer treatment. The mechanical properties of the blend films integrated with MA monomer were higher than that without monomer at the analogous conditions. The structural and morphological features of the films were examined by Fourier transform infrared spectroscopy and scanning electron microscopy, respectively. |
