A series of superabsorbent composites based on acrylic acid and modified Na-montmorillonite nanoclay with hydrolyzed collagen using N,N'-methylenebisacrylamide crosslinker (MBA) and potassium persulfate as an initiator (KPS) were synthesized through solution polymerization. Themolecular structure of sample was confirmed by Fourier transform infrared (FTIR) spectroscopy. Swelling behavior hydrogel composites have been studied in different medias such as slat solutions. Synthesized composites showed good thermal stability.
