Abstract
The phase behavior of the mixed catanionic surfactants in aqueous solution composed of the longchain ionic liquid IL NdodecylNmethylpyrrolidinium C12MPB and a divalent metal surfactant copper dodecyl sulfate CuDS2·4H2O was investigated The phase diagram of the catanionic system was mapped through visual observation and electrical conductivity measurement The formation of vesicles was confirmed in the lamellar phase Lα through transmission electron microscopy TEM Rheological measurements were used to study the macroscopic properties of the birefringent Lα phase Electrostatic and hydrophobic interactions are regarded as the main driving forces for the formation of vesicles Furthermore the vesicles were successfully used as the templates to prepare the leaflike CuO nanomaterials
