ABSTRACT
One of the most easily observed macroscopic properties of colloidal systems is their flow behavior, and it may range anywhere between a low viscous fluid and a gel state. The rheological properties and, in particular, the viscosity of microemulsions are macroscopically observable parameters that characterize a given system. Of course, the viscosity is a relevant quantity for many practical applications of microemulsions. For instance, pumping such systems might be of interest in their application, and here viscosity plays an important role.
