摘要：

The microemulsion system didodecyldimethylammoniumbromide (DDAB)/dodecane/water (electrolyte) has been investigated by means of phase diagrams and dielectric time domain spectroscopy (TDS). The microemulsion phase (L2) will gradually decrease upon electrolyte addition until only a narrow channel exists. The original microemulsions are built up by closed aggregates and bicontinuous structures depending on the location in the L2 phase. Dielectric parameters indicate that the electrolyte will gradually change the shape of the aggregates from elongated structures to spherical ones until the one-phase region vanishes. At 0.03 m NaBr only bicontinuous microemulsions exist. © 1991.
