The interaction between polymer and ionic surfactants has been studied in aqueous solution using dissipative particle dynamics (DPD) simulation. Mesoscopic properties of a polymer-surfactant complex were discussed in a molecular level, and the polymer morphologies in the surfactant solution were investigated using three dimensions coordinate. At the same time, the process of aggregation between polymer and surfactant was discussed using the endpoint distance of polymer. One conclusion is drawn that the aggregation morphologies of polymer in micelles solution can be obtained using DPD simulation method. With increasing the volume fraction of the surfactant, the polymer may have different configurations including free spread, elongated rod, a necklace of micelle pearls, extending in the hexagonal and lamellar phases.
