Abstract
Ellipsometry and surface light scattering allow the measurement of the rigidity constant and the structure of ultralow surface tension interfaces. We have measured the rigidity constant K of two surfactant monolayers at an oil/water interface. The first one is a monolayer with a very low K value and leads to the formation of bicontinuous phases, and we find K < kBT as expected. The second one is more rigid and gives rise only to the formation of birefringent phases, and we find K > kBT. Some information on the structure of the microemulsion oil or water interfaces is also obtained.
