Abstract

The structure of superabsorbent poly(acrylamide)-clay-based composite (SAPC) was studied by means of XRD, SEM, NMR, FTIR, TGA and DSC. The study showed that the acrylamide was intercalated in the lamina of clay in bimolecular layers. The hydrogels exhibited typical viscoelastic properties. The composite showed a strong response to changes in ionic environment (pH) and electric field strength, as well as chemomechanical properties.
