Abstract

We investigated the structural, mechanical, and swelling properties of composite hydrogels consisting of clay, a dispersing agent (tetrasodium diphosphate), and sodium polyacrylate (PAAS) prepared by mixing. Regardless of the simple preparation method, the gel exhibits excellent properties such as mechanical toughness and high swelling ability. For production of the tough gels, it is important to disperse clay particles using the dispersing agent and to use high molecular weight PAAS for formation of bridge connecting different clay particles in a dispersed state. Synchrotron small-angle X-ray scattering experiments reveal that PAAS was adsorbed on the positively charged edge of the clay particles.
