Abstract:

The morphology variations of the micelles under lid-driven flow were studied via dissipative particle dynamics simulations. The morphologies of the micelles under flow are different from that in equilibrium. The weak lid-driven flow has hardly changed the morphologies of micelles. We find the worm-like micelles under moderate lid-driven flow. In the strong lid-driven flow, smaller micelles are observed. The properties of the walls are also a dominant factor influencing the micelle morphologies.

Key words: Lid-driven flow; Block copolymer; Micelle; Dissipative particle dynamics
