A series of nanoclay-polymer composites (NCPCs) superabsorbents based on different types of nanoclays (10 wt%) were prepared by free-radical aqueous solution copolymerization reaction of partially neutralized acrylic acid and acrylamide using N,N’-methylenebisacrylamide (MBA) as a crosslinker and ammonium persulfate (APS) as an initiator. In present study the nanoclays were separated from three different types of soils and the effect of amorphous alluminosilicates on polymer/clay composite formation was also studied. In this paper, the reaction mechanism of the polymer composites incorporated with various clays was characterized by Fourier Transform Infrared Spectroscopy (FTIR) and Xray diffraction (XRD). The reaction between polymer and clay was related to the structure and properties of clays. The NCPCs were swollen in aqueous solution of urea and di-ammonium phosphate (DAP) fertilizer for nutrients loading to act as a release carrier of urea and di-ammonium phosphate (DAP). The investigation showed that incorporation of clays and its types had a great influence on equilibrium water absorbency as well as nutrient release rate and might be related to hydration and distention properties of the clays incorporated. |
