Abstract

Starch-based hydrogel is synthesized using gamma radiation. The hydrogel is then characterized to obtain the best ratio of hydrogel. Starch-grafted-acrylic acid hydrogels is produced using acrylic acid as monomer and starch from gadong tuber as co-monomer. Gamma radiation is used as cross-linking agent. Different volume of starch is used to produce hydrogels with different ratios of acrylic acid (AA) to starch. Hydrogels with ratio of 4:1 and 5:2 are synthesized. The reaction involved in the synthesis of hydrogel was a free radical polymerization. Swelling test for the starch-based hydrogel is carried out to observe the ability of hydrogel respond to the environmental change. Scanning Electron Microscope (SEM) is used to determine the morphology of hydrogel. The analysis of chemical structure is determined using the Infrared Spectrometer (IR). X-Ray Diffraction (XRD) is used to determine the present of amorphous component in the hydrogel. Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA) are used to determine the thermal stability of the hydrogel. Swelling test for this hydrogel is carried out in 5 different pH buffer solution with pH 3, 5, 7, 9 and 12 at a room temperature. In the buffer solution of pH 7, 9 and 12, the hydrogel with ratio 5:2 shows high value of swelling percentage compare to the hydrogel with ratio 4:1. However, in the buffer solution of pH 3 and 5, the hydrogel with ratio 4:1 swells more compare to the hydrogel with ratio 5:2. The peak showed in the IR proved that the present of the carboxyl group in the hydrogel after the polymerization process. From the thermogram of DSC and TGA, the hydrogel with ratio 5:2 showed higher value of glass transition compared to the hydrogel with ratio 4:1.
