Open full text 8 citations

Abstract

The formation of vesicles in aqueous mixtures of a single-chain anionic hydrocarbon surfactant, lithium dodecyl sulfate (LiDS), and a cationic fluorocarbon surfactant, bis (2-hydroxy ethyl) (2-hydroxy-3-perfluorooctyl propyl) methylammonium chloride (DEFUMAC), was confirmed. The vesicles were formed in all lamellar phase regions at a total surfactant concentration Ct of 10 mmol·dm-3. Vesicles size showed a wide range of distribution, the average becoming larger as the mixed ratio approached an equimolar ratio.
