A Novel Superabsorbent: Clay/Polyacrylamide Nanocomposite Hydrogel

摘要

A novel superabsorbent, clay/polyacrylamide nanocomposite hydrogels (S-M gel), has been successfully Prepared. It was found that the properties of S-M gel can be modulated by post treatment; the swelling ratio of S-M gels increases greatly by heat post treatment, much more than any other reported NC gels. Experimental results indicate that the improvements in swelling ratio are due to the physical structure changes of S-M gels. This funding will help to further investigate the structure of NC gels, and present a new approach to control the properties and structure of NC gels.
