VISCOSITY STUDIES OF WATER-CONTAINING REVERSED AOT MICELLES

The viscosities of water-AOT-carbon tetrachloride mixtures have been measured at 20°C for various AOT and H2O concentrations and molar ratios, [H2o] [AOT] ranging from 0 to 8. It is shown that an appropriate analysis of the data allows one to distinguish between solvation and micelle shape in their contribution to the viscosity of the solutions. Our results indicate that solvation rather than asymmetry is the principal cause of the observed deviations from the behavior of unsolvated spheres. © 1992.
