| Outline of Final Research Achievements |
When an external field is applied to a colloidal dispersion, a motion of colloidal particles called electrophoresis occurs. We clarified the physics of the non-linear response of electrophoresis in a strong external electric field. As the strength of the external field increases, the mobility of electrophoresis increases after the linear response region with a constant mobility, and then saturates. The physics of the nonlinear response is clarified based on the electric double layer dynamics. Then, we investigated the shear rheology of a dispersion in a viscoelastic fluid such as a polymer solution. We elucidated the mechanism of elastic shear thickening in a dilute dispersion that was observed experimentally, and succeeded in quantitative prediction of it by using direct numerical simulation.
