Abstract
Self-diffusion of all components in two different microemulsions has b een studied by the Fourier-transform pulsed-gradient spin echo H-1 nuc lear magnetic resonance technique. The analysis of hydrodynamic and di rect droplet-droplet interactions in microemulsions allows the simulta neous application of the Stokes-Einstein equation for surfactant and o il. The result of this analysis is a simple relation connecting self-d iffusion coefficients of components and the size of droplets. It is sh own that because of partial solubilization of water in oil the droplet radius can be significantly different from the expected radius. (C) 1 997 Elsevier Science B.V.
