论文摘要
在本文中，我们介绍了一个框架，以数值方式研究聚合物基质中纳米晶体的生长。该框架结合了熵弹性的鳞状理论与通常用于模拟晶体生长的相位场方法。我们特别研究了在存在拓扑约束（例如纠缠或交联）的情况下，结晶石的生长动力学，并表明可以观察到拓扑约束与生长动力学之间的耦合，可以观察到：可以观察到各种结构：看起来像球体或稳定的Nano-crystallites的分支结构。
In this article, we introduce a framework to investigate the growth of nano-crystallites in a polymer matrix numerically. This framework combines the Flory theory of entropic elasticity with phase-field approaches commonly used to model crystal growth. We investigate in particular the growth kinetics of a crystallite in the presence of topological constraints such as entanglements or cross-links, and show that depending on the coupling between the topological constraints and the growth kinetics various structures can be observed: branched structures looking like spherulites or stable nano-crystallites as observed in strain-induced crystallization.
