The self-assembly process of the surfactant molecules in aqueous solution was investigated using dissipative particles dynamics(DPD) simulation, and the aggregation morphology of the surfactant in solution was discussed by diffusio of the surfactant molecules. We found that DPD simulation can directly look into the assemble process, and with the increase of surfactant concentration, the aggregation morphology are divided into several structures, such as sphere micelle, mixed micelle of sphere and rod, rod micelle, hexagonal phase and lamellar phase.
