摘要
Microviscosity in AOT reversed micellar core, eta, was determined with a viscosity-sensitive fluorescent probe, auramine O (AuO), as a function of R (=[H2O]/[AOT]). With the increase in R, The eta decreased rapidly in the region of R<10, and leveled at about R=20. Auo molecules located in the vicinity of water/surfactant interface suggested the presence of water bound to polar heads of AOT.
