两亲性花生状纳米粒子的自组装
Self-assembly of amphiphilic peanut-shaped nanoparticles
摘要：
我们利用计算机模拟研究了Janus型两亲性花生状纳米粒子的自组装过程，发现了与分子表面活性剂研究中常见的堆积思想相一致的簇、双层和胶束相。然而，包装参数并不能解释我们观察到的分层自组装动力学，也不能解释双层和多面体的共存。这种共存表明，我们的模型的实验实现可以实现两个竞争有序结构中的任何一个的多能组装。
英文摘要：
We use computer simulation to investigate the self-assembly of Janus-like amphiphilic peanut-shaped nanoparticles, finding phases of clusters, bilayers and micelles in accord with ideas of packing familiar from the study of molecular surfactants. However, packing arguments do not explain the hierarchical self-assembly dynamics that we observe, nor the coexistence of bilayers and faceted polyhedra. This coexistence suggests that experimental realizations of our model can achieve multipotent assembly of either of two competing ordered structures.
