Abstract
Microemulsions are dispersions of oil and water, thermodynamically stable, transparent and very fluid. Their viscosity properties are known to depend strongly on microstructural changes. A Kneger-type formula has been used to model the viscosity variations in a well known model system where structural changes are promoted on salinity variations. The variations of the effective packing volume fraction follows the current expectations and reveal, for well defined values of the salinity, the formation of droplets clusters, the coalescence in the clusters, and the appearance of bicontinuous structures. Viscosity data of other less well known model systems have also been tentatively analyzed. Because viscosity reflects only indirectly the structural changes in a fluid, the analysis presented is still speculative. But it gives a very useful insight into the mechanism of microstructurai changes in micro-emulsions.
