Neutron small-angle scattering has been used to study the structure of an oil in water microemulsion in the critical region. The structure. one of small "swollen" micelles. is independent of the critical fluctuations. This together with other evidence strongly suggests that the latter are clusters o

โฆ Synopsis
Contrast variation neutron small-an@ scattering measurements have been made on microemulsions which, with the addition of salt, show transitions of the type Winsor I to Wiisor III to Winsor II. The structure of the Wmsor 11 am-l Winsor 1 phases are confumed as being respectively, d+ersiotls of water droplets in oil, and oiI droplets in water. For the Winsor III phase, where the volume fractions of OLI and water arc comparable, experrmental results are presented which constitute strong evidence in fwotu of M oil and water intercontiguous structure.

Small-angle neutron scattering has been used to determine whether or not a microemulston, contaming equal volumes of oil and water, has a bicontinuous structure. The spectrum. from the interfacial layer of surfactant and co-surfactant. shows the presence of distances both longer and shorter than tho
