Double layer, electric polyelectrolytic adsorbates

Fundamental investigation of the system at the molecular level. This requires investigations of the structure of the solid/liquid interface, namely the structure of the electrical double layer (for charge-stabiUsed suspensions), adsorption of surfactants, polymers and polyelectrolytes and conformation of the adsorbed layers (e.g., the adsorbed layer thickness). It is important to know how each of these parameters changes with the conditions, such as temperature, solvency of the medium for the adsorbed layers, and the effect of addition of electrolytes. 

It has already been mentioned and it is further illustrated in Figure 8.14 that the viscosity depends a great deal on the shape of the particles. It also depends on the adsorbed polymers, for sterically stabilized dispersions, especially for polyelectrolytes, as the electrical double-layer (Chapter 10) also travels with the particle. Actually, the charges on dispersion or emulsion particles affect the viscosity in three different ways the already mentioned distortion of the electrical double layer by the shear flow, double layer repulsion between particles and - for...
