Thermodynamic properties and contact angles of CTAB and SDS in acetone–water mixtures at different temperatures

The thermodynamic properties of sodium dodecyl sulfate (SDS) and cetyltrimethylammonium bromide (CTAB) in neat water and acetone–water mixtures were studied by measuring the conductivity at 298.15, 308.15, 318.15 and 323.15 K.
