摘要

A novel Lasoda-based hydrogel was synthesized and optimized using a microwave-assisted method. Various reaction parameters, including initiator concentration, solvent volume, reaction time, monomer concentration, microwave power, pH, and crosslinker concentration, were systematically optimized to obtain a hydrogel with maximum swelling capacity. The optimized hydrogel was characterized using various advanced techniques, including FTIR, FESEM, NMR, BET, TGA, and DTG. Rheological studies, including strain sweep, oscillatory frequency sweep, and thixotropy tests, were conducted. Creep-recovery behaviour determined from compliance-time plots was investigated at room temperature and pH 7. The results demonstrate both viscoelastic and elastic deformation behavior of the prepared hydrogel. The stiffness of the hydrogel was evaluated using the Young’s modulus time plot. Furthermore, the hydrogel exhibits pseudoplastic and shear-thinning behavior, as evidenced by its viscosity-shear rate and viscosity-frequency curves, respectively.
