摘要: The effect of different gamma-ray irradiations on the functional groups and mechanical properties chitosan, collagen, chitosan/collagen blend have been studied. Commercially available chitosan extract collagen from bovine tendon by acid dissolution method were employed. Chitosan, membranes prepared using solvent evaporation method. dried subjected to irradiation 0, 15, 25 kGy. then characterized Infrared spectroscopy measured in tensile elongation at break. irradiated displayed reduced intensity -OH, -CH, -NH -C-O-C groups, whereas, revealed amide I, II III groups. (50/50%) demonstrated decreased intensities –OH application had produced with a strength break between membranes. It was further determined that decrease likely be due some changes
