论文摘要
基于可变形的纳米颗粒（NP）铰链设计可重新配置的材料，以了解对这些NP可以采用的能量最受欢迎的形状。使用仿真，我们表明，由janus斑块，条纹和多面体分布的斑块等表面电荷图案量身定制的空心，可变形的斑块NP，对图案和离子强度的变化的响应，将其形状不同地适应，并转化为胶囊，半球，变量尺寸为碗，碗和多面角。讨论了NP表面电荷，形状和弹性能量密度的各向异性之间的联系。
Designing reconfigurable materials based on deformable nanoparticles (NPs) hinges on an understanding of the energetically-favored shapes these NPs can adopt. Using simulations, we show that hollow, deformable patchy NPs tailored with surface charge patterns such as Janus patches, stripes, and polyhedrally-distributed patches differently adapt their shape in response to changes in patterns and ionic strength, transforming into capsules, hemispheres, variably-dimpled bowls, and polyhedra. The links between anisotropy in NP surface charge, shape, and the elastic energy density are discussed.
