Abstract

The nanocomposites of poly(acryl amide-co-acrylic acid) with NaY and Clinoptilolite were prepared using ammonium persulfate as an initiator and N,N′- methylene bis acryl amide as the cross-linker. The morphology was characterized by SEM and the structure of nanocomposite materials was studied with XRD and FT-IR that showed the interaction between porous materials and poly(AAm-co- AAc). Thermo gravimetric analyzer (TGA) curve shows that all the chain-extended poly(AAm-co-AAc) are stable up to 250 °C and maximum weight loss occurs at 890 °C. The TGA results indicated higher stability for poly(acryl amide-co-acrylic acid)/NaY and Clinoptilolite composites than poly(AAm-co-AAc). The adsorption and desorption behavior of methylene blue were investigated for nanocomposites. It was shown that poly(AAm-co-AAc)/NaY and Clinoptilolite nanocomposites have higher adsorption than NaY, Clinoptilolite and poly(AAm-co-AAc) alone. This effect was attributed to good interaction between the hydroxyl group in porous materials and carboxylic group in poly(AAm-co-AAc) with methylene blue.
