Investigation on the Mutual Interplay between the Physicochemical Properties of 1-octyl-3-Methylimidazolium Bromide, [C8mim][Br], and CuO Nanofluids by Measuring the Electrical Conductivity, Surface Tension ,and Static Contact Angle

The present study was undertaken to investigate the effect of temperature on the micelle characteristics and synergy of [C8mim][Br] in the presence and absence of CuO NPs into the bulk and interfacial of air/water using the data obtained from measuring the electrical conductivity. The specific conductance was measured as a function of the [C8mim][Br]concentration at pure water and with 0.01 wt%, 0.005 wt%, 0.00066 wt% of CuO nanofluids as the solvent at; 288.15, 293.15, 298.15, and 303.15 K. In order to clarify whether the residence of CuO at different concentration can affect on Thermodynamic of Micellization, the specific conductance (κ) versus the concentration dependence of ionic liquid, m, was measured at different temperatures. the experimental conductivity for the aqueous solutions of [C8mim][Br] measured at (288.15, 293.15, 298.15 and 303.15) K are given.
