研究了微重力环境中磁性椭球纳米粒子在切换磁场驱动下的悬浮结构。悬浮液在外加磁场中变粗,但由于其剩余磁性引起的吸引力,不会完全相分离。粗化的结构和动力学取决于颗粒的纵横比。椭球体的粗化与高宽比有关,取决于场强和触发频率。较长的椭球体()形成长纤维结构,其横向聚集的动力学对现场条件不太敏感。这些结果表明胶体相互作用,颗粒形状,和驱动场,可用于控制悬浮液的微观结构之间的相互作用。
The suspension structure of magnetic ellipsoid nanoparticles is studied as they are driven by toggled magnetic fields in a microgravity environment. Suspensions coarsen in the applied field, but do not phase separate fully due to attraction induced by their remenant magnetism. The structure and kinetics of coarsening depend on the aspect ratio of the particles. The coarsening of ellipsoids with aspect ratio depends on the field strength and toggle frequency. Longer ellipsoids () form long fibrous structures that aggregate laterally with kinetics that are less sensitive to the field conditions. These results suggest an interplay between colloidal interactions, particle shape, and driving field that can be used to control the suspension microstructure.
