Conductomery Properties of Mixed Reverse Micelles with Amphiphilic Ionic Liquids

Abstract:

The conducting properties of mixed reverse micelles formed with amphiphilic ionic liquids (DomimBF4) and cetyltrimethylammonium bromide (CTAB) have been investigated, with the emphasis on the effect of cosurfactants, surfactant compostion. In DomimBF4/CTAB/ n-butanol/ cycloheane system, a percolation in conductance phenomenon was observed, the percolation threshold Wp depends upon the content of DomimiBF4. The influence of cosurfactants on the conductomery properties of mixed reverse micelles was studied in detail.
