Effect of Addition of Polymer on the Rheology and Electrokinetic Features of Laponite RD Aqueous Dispersions

- May 17, 2009


Technical Paper - Rheological properties and zeta potential are investigated for 1 % Laponite RD aqueous dispersions with different contents of poly(ethylene glycol). At low concentrations of polymer (< 1 %), the clay dispersions are stable, whereas an unstable liquid phase appears above 2 % polymer. The samples present a Newtonian behavior, showing more viscous than elastic response. The viscoelastic moduli are...
