Abstract: Native cellulose (NC) was used as raw material for synthesizing a novel native celluloseg- polyacrylamide (NC/PAN) superabsorbent composite by graft polymerization with native cellulose powder and acrylamide in aqueous solution, using, N,N′-methylenebisacrylam- ide as a crosslinker and ammonium persulfate as an initiator. The water absorbency of superabs- orbent composite is 500 g g-1 in distilled water,which was characterized by Fourier transform infrared (FTIR) pectroscopy, scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The results of FTIR spectra showed that the product was a composite based on PAN incorporating with NC. The introduced NC enhanced thermal stability and carbon-residue of the PAN superabsorbent and formed a loose and more porous surface.
