摘要：

The bending elastic energy of a surfactant monolayer at the oil-water interface in a microemulsion system can be described by the spontaneous monolayer curvature and two elastic constants kappa and <(kappa)over bar>. Here we present the determination of these constants by a combination of dynamic light scattering and neutron spin-echo spectroscopy for the octane-C10E5-water microemulsion on the water continuous side of the phase diagram. Small-angle neutron scattering data are also presented and compared to the light scattering results.
