Abstract

Poly(ethylene oxide) and Laponite, a synthetic hectorite clay, form highly viscoelastic solutions in water. Above a certain clay concentration, these solutions can be described as physical crosslinked networks where clay platelets undergo equilibrium adsorption/desorption with polymer chains. Complex fluids such as these containing anisotropic clays have generated significant interests both in shear induced structural changes and in network dynamics. The interactions of polymer/clay solutions were characterized using dynamic rheology measurements and stress relaxation experiments.
