摘要：

The size and polydispersity of AOT water/oil microemulsions were measured by time-resolved fluorescence quenching. From the measured volume polydispersity the radius polydispersity was derived and calculated. An average polydispersity of 15.7% was obtained. No trends in polydispersity values at different droplet sizes or different solvent chain lengths were observed. The polydispersity values obtained are compared with values obtained by a new approach to theoretically estimate the polydispersity, and approximate values for the interfacial tension, gamma(infinity), of the planar oil/water interface and the interfacial bending constant, K, were computed.
