Relation between Exchange Process and Structure of AOT Reverse Micellar System

Abstract

The decreases of the exchange micellar rate constant, determined from stopped flow kinetic study, and of the sticky parameter, determined by small angle X-ray scattering, with the water volume fraction are strongly correlated. This phenomenon is explained according to the contact value of the micelle−micelle correlation function and the surfactant monolayer rigidity. It is shown that the attractive interactions govern the decrease of the exchange process with the increase in the number of droplets.
