The dynamic properties of concentrated charge stabilized suspensions

The equilibrium properties and flow behaviors of concentrated charge stabilized suspensions are investigated in this dissertation. Monodispersed polystyrene particles with diameters ranging from 35 nm to 250 nm are used. Suspensions with volume fractions ranged from 0.10-0.62 are examined. Equilibrium elastic moduli and osmotic pressures are characterized. Rheological and osmotic pressure determinations of the location of the order/disorder phase transition are found to agree. Yielding and catastrophic shear thinning where the suspension viscosity decreases discontinuously with increasing shear stress are measured with both constant stress and constant strain rate rheometers.
