| 摘 要： | l ntroductionMicroemulsiolls are transparent and nuid systems composed of water, oil andamphiphilic molecules. They form spontaneously with simple mixing. Microemulsionsmay be water- or oil- continuous and bicontinuous under some conditions of temperatureor composition. Middle phase microemulsions(MPME) is called the 'bicontinuousstate' which is considered to be a sponge-like random netWork. Owing to its ultralowinterfacial tellsiolls against the excess water and oil phase with which they ar…

| Abstract: | Dielectric measurements were performed on middle phase microemulsions composed of sodium dodecylsulfate (SDS), cetyltrimethylammonium bromide(CTAB), n-butanol, n-heptane and brine. Distinct and unique dielectric behavior , with characteristic frequency dependence regularity on the salinity of the microemulsions, was observed in the low-frequency range from 10- 103Hz. It can be considered to be an interfacial polarization mechanism. |
