摘要: We have used a custom-built ultrasound velocimeter to carry out high-precision velocity measurements of reverse micelle solutions, made ionic (AOT) and nonionic (C12E4) surfactants in oil, as function water concentration. show that the observed variation increasing concentration differs from characteristics surfactant polar headgroups. The complex profile compressibility curves obtained densimetric can be accounted for by relation existing between surface headgroup each number interacting molecules. At highest concentration, parameters are different those reported “bulk” reflect peculiar properties confined water.
