Structure of Phosphate Fluorosurfactant Based Reverse Micelles in Supercritical Carbon Dioxide

The existence of microemulsions in the system composed of phosphate-based fluorosurfactant, water, and supercritical CO2 is demonstrated by small-angle neutron scattering experiments. A computer simulation study performed on a reverse micelle created in this system shows that the micelle remains stable over a 4 ns time period of the simulation. While the data obtained from the experiments provide information about the size of the reverse micelle, the data obtained from the simulations provide additional information about the shape and structure of such a micelle.
