![]() ![]() It was concluded that G-Cs films prepared by gamma irradiation have improved their mechanical properties than the gelatin itself. ![]() FTIR spectral analysis showed that gelatin and chitosan formed a crosslinked network. At optimum conditions ( 30 kGy and 75% Cs), the gel fraction, tensile strength, and elongation at break were higher leading to a stronger composite films as compared to the gelatin film. Chemical changes of the films were measured by FT-IR, gel fractions were determined by gravimetry, and mechanical properties were determined by tensile strength and elongation at break using universal testing machine. In this study, gelatin solution was mixed with chitosan solution in various ratios (G/Cs: 100/0, 75/25, 50/50, 25/75, 0/100), casted at room temperature to make composite films, then tested for the effectiveness of various gamma irradiation doses (10-40 kGy) for crosslinking of the two polymers. Chitosan (Cs) is a biodegradable polymer, which has biocompatibility and antibacterial properties. Gelatin (G) is prone to degrade or dissolve in water at room temperature, therefore to enhance its lifetime, it has to be modified with other compound such as chitosan. Nowadays, attention has increased concerning the application of gelatin.The aim of this research was to improve the mechanical properties of gelatin produced from fish scales, which concurrently could increase the usefulness of fish scales. Gelatin is an important component of fish scales. International Nuclear Information System (INIS)Įrizal Perkasa, D.P.
