摘要/Abstract

摘要：

利用耗散粒子动力学模拟方法研究了顶盖驱动方腔流条件下, 线性两嵌段共聚物胶束形态的变化. 结果表明弱的流场对胶束的形态影响不大, 但是在中等强度流场的作用下, 小胶束会融合并形成条状胶束, 而在很强的流场作用下, 胶束会被破坏而形成体积更小的球状胶束.

关键词: 顶盖驱动流; 嵌段共聚物; 胶束; 耗散粒子动力学

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
