Effect of Starch and Chitosan Addition on Swelling Properties of Neutralized Poly(Acrylic Acid)-Based Superabsorbent Hydrogels Prepared by Using γ-Irradiation Technique

Superabsorbent hydrogels are polymers with a 3D network that have attracted the attention of scientists and industrialists because their fantastic ability to absorb retain water aqueous solutions. The most widely used commercially available superabsorbent synthetic K-acrylate materials. In this novel study, been developed using natural ingredients more biodegradable properties. were synthesized from acrylic acid, cassava starch, chitosan γ -irradiation method under different experimental conditions. γ-irradiation technique was chosen produce free residues may remain when chemical crosslinkers used. effects irradiation dose, acid composition, amount starch on characteristics produced analyzed. resulting further characterized by fourier transform infrared spectroscopy (FTIR) scanning electron microscope (SEM) evaluate structure. thermal behavior products at neutralization doses tested differential calorimetry (DSC). FTIR data indicated grafting reaction successfully implemented in work. SEM analysis showed hydrogel study porous there reduction pore size addition chitosan. It can be concluded affects acid-based properties, which size, , gel content, antibacterial activity, swelling capacity water, salt, urea best obtained adding 0.25 g chitosan, 50 % 5 kGy . graft possess maximum 670 g/g for distilled 520 NaCl solution, 767 solution (relative dry weight). These sterile Escherichia coli bacteria had potential applied as resins various fields.
