Abstract

In general, the physical properties of colloidal dispersions are altered when polymer is added to the continuous (liquid) phase. Such changes arise in part from polymer adsorption or depletion effects at the particle (or droplet or bubble)/solution interface, but also in part from the increase in polymer concentration in bulk solution. Basically, the physical properties of colloidal dispersions reflect two classes of interactions that are present: thermodynamic and hydrodynamic. The thermodynamic interactions arise from the various types of interparticle forces and these determine, together with the particle volume fraction, the osmotic pressure and equilibrium structure of the dispersion. This structure may be a single stable (gas-, liquid-or solid-like) colloidal phase, two (or more) co-existing colloidal phases, or a coagulated system. On the other hand, the hydrodynamic interactions control in part all dynamic processes occurring, such as diffusion, sedimentation, electrophoresis and aggregation. If polymer adsorption occurs then the size of the primary hydrodynamic unit increases but, at least for dilute polymer solutions, it is the solution viscosity which η mainly controls the process rate R (in general, R ∼η−1). In semi-dilute and concentrated polymer solutions, the viscoelastic properties of the polymer solution have to be considered. In concentrated dispersions the hydrodynamic interactions become multibody and complex. The reader is referred to the text “Colloidal hydrodynamics” by Van der Ven [1] for further details.
