Abstract

The technique of photon-correlation spectroscopy and its application to the determination of the size of micro-droplets of water dispersed in an oil phase is described. The phase behaviour of ternary systems formed by M2+ (AOT)2/water/cyclohexane is reported (where M2+ = Mg2+ and Ni2+) and compared with the corresponding Na(AOT) phase diagram. Diffusion coefficients of the aggregate structures have been determined by PCS and in combination with data from other techniques, the structure and interactions of the aggregate system in the water-in-oil microemulsion domain can be described.
