Dielectric studies on nonionic microemulsions
A microemulsion is a clear, stable isotopic fluid prepared from an oil, water, and an emulsifier. Many of these systems appear to be thermodynamically stable single phases, and can be essentially monodisperse swollen micelles of diameter 6 to 60 nm. Because of the very large surface-to-volume ratio of the dispersed phase, these systems are well suited for studying the modification of the properties of the interfacial layers of water by the presence of the oil and emulsifier. In this study, the dielectric properties of oil/water microemulsions prepared from hexadecane and water in various proportions, with an emulsifier consisting of the nonionic surfactant polyoxyethylene 20 sorbitan monostearate (TWEEN 60) and n-pentanol as cosurfactant, are studied. 35 references.
