Crosslinked CMC-N/PAAm hydrogel were prepared using electron beam irradiation. The factors affecting the degree of crosslinking and swelling behavior of the prepared copolymer were determined. As the irradiation dose and/or PAAm concentration increase, the gel content increases. Preparation of super-porous hydrogel was attained by the addition of ammonium carbonate as a gas-blowing agent during the irradiation process. The surface morphology and pore structure of such a prepared hydrogel were examined using scanning electron microscopy. The ability of the prepared hydrogel to absorb and retain large amount of water and as simulating urine was measured. The results suggested the possible use of CMC-Na/PAAm hydrogels in the personal care product industry.
