标题： Theory of Microphase Separation in Elastomers

摘要： 受最近实验的启发，我们提出了一种在溶剂膨胀的弹性体中微相分离的相场模型。 混合物分子尺度与弹性作用的介观尺度之间的不平衡产生了有效的长程相互作用，形成了稳定的有限尺寸域。 我们关于域尺寸和转变温度与弹性体刚度依赖关系的预测与实验结果高度一致。 分析相图结合数值结果，捕捉了微相形态的丰富性，为创建适用于各种应用的稳定图案弹性体铺平了道路。 显示英文摘要

摘要： Inspired by recent experiments, we present a phase-field model of microphase separation in an elastomer swollen with a solvent. The imbalance between the molecular scale of demixing and the mesoscopic scale beyond which elasticity operates produces effective long-range interactions, forming stable finite-sized domains. Our predictions concerning the dependence of the domain size and transition temperature on the stiffness of the elastomer are in good agreement with the experiments. Analytical phase diagrams, aided by numerical findings, capture the richness of the microphase morphologies, paving the way to create stable, patterned elastomers for various applications.
