Application Potential of Temperature-Responsive Polyaspartic Acid-Based Superabsorbent Composites in Abiotic Stress Environments.

ABSTRACT: Superabsorbent composites (SACs) play a crucial role in mitigating issues related to abiotic stresses such as soil drought and salinization. However, high costs and various environmental challenges severely limit their widespread application. Herein, low-cost inorganic clay diatomaceous earth (DT), biodegradable polyaspartic acid (PASP), acrylic acid (AA), and N-isopropylacrylamide (NIPAM) were utilized as raw materials to synthesize PASP-g-P-(AA-co-NIPAM)/DT SACs through aqueous free radical polymerization. The water absorption properties of SACs were optimized by varying the reactant content. The water uptake capacities in distilled water, tap water, and 0.9 wt % NaCl solutions were 672.7, 147.9, and 80.4 g g^-1, respectively. Additionally, the SACs were ev
