微相平衡与组装动力学

Microphase Equilibrium and Assembly Dynamics

Yuan Zhuang, Patrick Charbonneau

摘要:

尽管有许多尝试,有序的平衡微相尚未获得实验胶体悬浮液。最近对微观的、基于粒子的微相形成剂的平衡相图的计算[Zhuang等人,物理修订信函116,098301(2016)]发现这种中尺度组件是热稳定的。在这里,我们考虑他们的平衡和组装动力学。在中间密度以上的有序-无序过渡,我们确定了四个不同的动力学制度和结构变化的基础上的动力学交叉从一个无序制度到下一个。在有序-无序转变下,我们还发现,周期性的laminates是最动态可访问的周期性微相。因此,我们的分析提供了一个全面的看法,无序的微相动力学和路线的组装周期性微相在一个假定的良好控制的实验系统。

英文摘要:

Despite many attempts, ordered equilibrium microphases have yet to be obtained in experimental colloidal suspensions. The recent computation of the equilibrium phase diagram of a microscopic, particle-based microphase former [Zhuang et al., Phys. Rev. Lett. 116, 098301 (2016)] has nonetheless found such mesoscale assemblies to be thermodynamically stable. Here, we consider their equilibrium and assembly dynamics. At intermediate densities above the order-disorder transition, we identify four different dynamical regimes and the structural changes that underlie the dynamical crossovers from one disordered regime to the next. Below the order-disorder transition, we also find that periodic lamellae are the most dynamically accessible of the periodic microphases. Our analysis thus offers a comprehensive view of the disordered microphase dynamics and a route to the assembly of periodic microphases in a putative well-controlled, experimental system.
