THE LYOPHILIC STRUCTURE-MECHANICAL BARRIER AS A FACTOR OF DISPERSION STRONG STABILIZATION

摘要

The lyophilic structure-mechanical barrier formed by the interfacial adsorption layer is considered as a factor of strong stabilization of disperse systems with respect to high concentrations of disperse phase and electrolyte. Such barrier must possess two principal features: intrinsic mechanical strength of the layer - preventing coalescence, and high affinity of the external side of the layer and dispersion medium - opposing coagulation; independent experimental approaches for their quantitative characterization are presented.
