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.
我们使用计算机模拟来研究类花生形两亲性纳米粒子的自组装,发现了与分子表面活性剂研究中熟悉的包装概念一致的团簇、双层和胶束相。然而,包装论点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形的共存。这种共存表明,我们模型的实验实现可以实现两种竞争有序结构中任意一种的多潜能组装。
