Self-Assembly Behaviors and Flow Properties of Amphiphiles by Mesoscale Simulations with Hydrodynamic Interactions

Research output: Contribution to journalArticlepeer-review

Abstract

Amphiphilic molecules or colloids such as surfactants and Janus particles with hydrophobic and hydrophilic parts can spontaneously self-assemble in a variety of morphologies in their solutions. Coarse-grained simulations can be used to investigate the behavior of molecules inside these complex fluids and clarify the origin of rheology. However, the choice of essential degrees of freedom and kinetic equations for their dynamics must be carefully considered. Indeed, the hydrodynamic interactions play essential roles for the dynamics of solutions. This article overviews a few simulation techniques that are suitable to the problems mentioned above. The results for surfactant aqueous solutions under confinement and Janus colloid dispersions under shear are exhibited as well as typical examples.
