AB - A series of novel superabsorbent nanocomposites based on 2-hydroxyethyl methacrylate (HEMA) and acrylamid (AM) were 
prepared via in situ free radical polymerization, using clay (Laponite XLS) as a crosslinker and ammonium persulfate (APS) 
as an initiator. The structure and surface morphology of the superabsorbent nanocomposites were characterized by Fourier 
transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron 
microscopy (SEM). The water absorbency was found to be 612.5 and 182.6 g H_2O^{g-1} in distilled water and 0.2% NaCl 
solution, respectively. In addition, the superabsorbent nanocomposites reported here might be a potentially smart material 
in some range of applications including adsorption materials, superabsorbent fiber and drug-delivery devices.
