Dissipative Particle Dynamics Simulation of Interface Tension in the Ternary Triton X-100/Toluene/H2O System
The assembly behavior of the nonionic surfactant Triton X-100 at the water/oil interface was studied on the mesoscopic level using a dissipative particle dynamics simulation.We extended the calculation method for interracial tension from a binary water/oil system to a ternary system with surfactants.In particular,the simulated results of interfacial tension that were chosen for illustration are in excellent agreement with the experimental results.Additionally,we discuss the relationship between interfacial tension and interfacial density,which supports the synergistic theory of mixed surfactants.The microscopic information obtained from the simulated method will opens another door for the selection and application of surfactants in enhanced oil recovery.
