Abstract

Organic-inorganic hydrophilic composites based on sodium polyacrylate (PAANa) and poly-N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (PAPTMS) showed the improved swelling capacity at incorporation of PAPTMS. Changing of non-Fickian to Super case II swelling behaviour is observed at 20 wt % PAPTMS content. Enhancing of thermal stability and heat-resistance index of composite hydrogels compared to PAA is shown.
