Novel superabsorbent polyacrylate hydrogels reinforced with nanotitanates: Study of swelling, mechanical and rheological properties
Year: 2026
Type: article
Abstract: Herein, a novel polyacrylate hydrogels incorporated with nanotitanates (NT@PAA) were synthesized using different schemes in order to obtain a robust, stable and efficient superabsorbent hydrogel. It was observed that the overall reaction volume, concentration of NaOH, amount of crosslinker and NTs played a significant role in achieving the target properties. The hydrogels were systematically investigated for their swelling behaviour, mechanical strength, and rheological properties. The incorporation of NTs into the PAA matrix led to a 32.85% increase in the swelling %, and the load-bearing capacity increased by 178.65% compared to native PAA. Rheological studies of the NT@PAA, comprising frequency sweep and LVR determination, showed a higher value of storage modulus (G’) as well as a higher stress (τ) value at the end of LVR in comparison to the native PAA. Overall, the study indicated the formation of a reinforced NT@PAA network with improved load bearing, structural stability, and functional performance.
