The structural effect of urea in sodium bis(2-ethylhexyl) sulfosuccinate (AOT)/n-hexane/water reversed micelles (RM) at molar concentration ratio [water]/[AOT] = 10 is investigated by light and small angle X-ray scattering techniques. Scattering intensities are analyzed within the framework of repulsion and attractive interaction potentials due to RM excluded volume (hard sphere term) and contact adhesion (attractive term). In the absence of urea the simple hard sphere droplet model up to a RM volume fraction (phi) of 0.32 applies for the entire scattering curves. In the presence of 3 and 5 M urea, light scattering intensities can be fitted only by including in the model an attractive term. X-ray data with 5 M urea show that RM preserves its discrete nature even for phi’s where ionic percolation occurs. Results are interpreted by preferential solubilization of urea at the interfacial region decreasing its stiffness (appearance of attractive interaction) without the formation of a bicontinuous phase. Accordingly the increase in the solution conductance previously observed with these mixtures is a result of clustering of RM droplets without their fusion.
