Dual-Responsive Hydrogel Composite Bearing Schiff-Base Linkages: Water Retention Coupled with Controlled Fertilizer Release
Conventional superabsorbent hydrogels mostly rely on synthetic polymers and are often costly and environmentally persistent, while conventional fertilizers suffer from rapid leaching and volatilization. There is a pressing need to develop materials based on natural biodegradable polymers that serve as a water reservo...
