Through analyzing three dimensional structures of aggregates, three simulated results are found. One is the phase separation, which is clearly observed by water density and the aggregates in the simulated cell; another is the water morphology in reverse micelle, which can be found through the isodensity slice of water including bound water, trapped water and bulky water; the third is about the water/oil interface, i.e., ionic surfactant molecules, SDS, prefer to exist in the interface between water and oil phase at the low concentration.展开更多
