Research Abstract

At the interfaces between air and aqueous surfactant solutions, surface wave called a ripplon is generated due to molecular motions of constituents and the ripplons scatter lights irradiated to the surfaces. In this study, the surface quasielastic light scattering(SQELS) apparatus was designed and constructed. The surface tensions and dilational viscoelasticity of ionic and nonionic surfactant solutions were evaluated using the SQELS.
