A series of poly (N-cyclohexylacrylamide-co-Acrylamide/Maleic acid) /OMMT nanocomposite hydrogels (NC) were prepared from free-radical copolymerization in water/methanol medium using ammonium persulfate (APS) as a free radical initiator and N,N’- methylene-bis-acryl amide(MBA) as the cross-linker at 60˚C. The nanocomposite hydrogels were synthesized via in situ polymerization using organo modified MMT (O-MMT) nano clay. The optimum swelling of nanocomposite superabsorbents was achieved at 0.150g of OMMT nanoclay. The synthesized nanocomposites were characterized by FTIR, SEM, XRD and TGA techniques. Swelling and diffusion parameters in water and dye solution were calculated. The effect of two cationic salt solutions on the swelling was studied. The hydrogel nanocomposites showed up to 99.9% removal efficiency towards methylene blue dye adsorption study.
