Enhancement of water absorption properties of potassium polyacrylate-based hydrogels in CaCl2-rich soils using potassium di- and tri-carboxylate salts A series of potassium polyacrylate hydrogels (KPAHs) hyperabsorbents of water 0.08, 0.21, and 0.46 wt% of triethylene glycol dimethacrylate (TEGDMA) crosslinker were prepared by a free radical…

Researchers report #potassiumpolyacrylate #hydrogels enhanced with KDC/KTC, showing exceptional swelling and restored water absorbency in 3–9 g L⁻¹ CaCl₂, offering an eco-friendly solution for #AgriculturalWater retention.
