Viscosity measurements were performed in water/AOT (sodium bis(2-ethylhexyl) sulfoccinate)/isooctane microemulsions as a function of temperature between 25 and 55°C, molar ratio W 0  = water/AOT ranging from 3 to 45 and three values of AOT/isooctane volume fractions (Φ m = 0.1, 0.15, and 0.2). It was shown that microemulsions behaved as Newtonian fluids in the studied range of shear rate. For a critical molar ratio, W 0c , the corresponding viscosity, η 0c , was shown to be constant with temperature but dependent on the micellar concentration. For W 0  &lt; W 0c , the solutions behaved as simple fluids and the temperature dependence of viscosity was described by an Arrhenius law. The total activation energy was found to be dependent on W0 with a maximum for W 0  = 5. A correlation between the microscopic structure of the reverse micelles and the total activation energy was proposed. However, a complex fluid behavior was observed for W0 &gt; W0c, where the viscosity increased with temperature. For some values of W 0 , the viscosity reached a maximum, which could be explained by attractive interdroplet interactions and formation of droplet clusters.
