Dynamic Behavior of Microemulsions
The dynamic behavior of water-in-oil microemulsions has been studied by using different techniques: light scattering, electrical conductivity, viscosity and electrical birefringence measurements. A tentative picture of the inversion process from water-in-oil to oil-in-water structures is presented. When the interfacial layer is relatively rigid,droplets can be concentrated to large volume fractions and inversion is relatively sharp. Where the interfacial layer is more fluid the structure of the droplets disappears progressively above the percolation threshold,and in the very large inversion region the structure is probably bicontinuous.
