Experiment and simulation studies on the mesostructures of gemini (12-3-12,2Br−)-SDS-H2O ternary

For simulations, we adopted dissipative particle dynamics (DPD) technique. With carefully chosen parameters, especially the conservative term, we could reproduce a great variety of mesostructures including spherical micelles, rodlike micelles, planar micelles, network with junctions, bilayer membranes as well as multilamellar aggregates, most of which can be found in corresponding experimental work. DPD results also reveal vividly the self-assembling mechanism that the dispersed surfactant molecules are organized to form small micelles, then fused and twisted to encapsulate water to form vesicles.
