Connected-disperse systems viscosity

The viscosity in connected-disperse systems with coagulation structures changes more abruptly than the viscosity in free-disperse systems. In this case, one can encounter an entire spectrum of states between two limiting cases that of a completely intact structure and one corresponding to the... 

Macromolecular colloid solutions also play an important role in ensuring the stability of disperse systems (e.g. suspensions, emulsions). In the case of emulsions the polymer decreases the rate of separation by increasing viscosity on the one hand, and it has an enthalpy stabilizing effect by adsorption on the surface of the droplets on the other hand [3, 4, 7]. Depending on the concentration of the polymer, a protecting and flocculating effect can be observed during the interaction between suspensions and polymers. If the polymer concentration is low, the polymer adsorbed on the surface of the particles connects the particles into loose floccules. Thereby, the rate of... 

This formula may be useful as a rheological method for determining the thickness of adsorption layer, which is formed as a result of interaction between a dispersion medium and filler, by the results of measuring the t] versus q> dependence. Especially curious phenomena, connected with surface effects, arise when a mixture of fillers of different nature is used according to concentration of an active filler the introduction of the second (inert) filler can either increase or decrease the viscosity of a multicomponent system [35],... 

For a two-liquid mixture system, one liquid may form droplets, dispersed into another continuous liquid phase. Under an electric field, the liquid droplet may behave like a solid particulate, polarized and aligned along the direction of the electric field. A liquid-droplet bridge may form and connect two electrodes. Therefore, the viscosity of the whole system may be detennined by the viscosity of the fibrillated liquid droplet. If the viscosity of this liquid droplet phase is lower than that of the continuous phase, a negative ER effect is thus expected. Which liquid would form the droplet is dependent on the relative concentration of those two liquids. This is the reason that the viscosity and the concentration of two liquids are important for the system to show a positive or a negative ER effect.
