摘要：
The conductivity of water/ClPFPE-NH4/scCO(2) systems is studied over a wide range of pressures and droplet volume fractions at 35degreesC and at two constant water-to-surfactant molar ratios, W-0 = 10.3 and 18.7, respectively. The results are interpreted according to three different models for low, intermediate and high concentrations of water and surfactant. Information is obtained about a possible bulk-like behaviour of water, about the approximate size of the micelles, about micellar percolation, and about changes of CO2-water droplet interactions with pressure.
