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.
