AbstractA novel superabsorbent composite simultaneously incorporated with both attapulgite and Na-montmorillonite was prepared by aqueous polymerization using N,N’-methylenebisacrylamide as a crosslinker and ammonium persulfate as an initiator. The effects of the clay content on swelling ability of the superabsorbent composite were investigated. The superabsorbent composite were characterized by IR, XRD and SEM. The results indicate that Na-montmorillonite was exfoliated in the composite, whereas, attapulgite kept its crystalline structure. The content of clay has great influence on surface morphology and water absorbency of the superabsorbent composite, and the collaborative effect of attapulgite and Namontmorillonite on swelling ability is superior to that of single one.

Poly Acrylic Acid

A novel superabsorbent poly(acrylic acid)/montmorillonite composite with water absorbency of about 1100 times its own weight (g H2O/g) was synthesized by graft copolymerizing acrylic acid onto ultrafine montmorillonite powder. The influence of the amount of crosslinker, montmorillonite and neutralization degree on the water absorbency of the composites is discussed in this paper.
