| Outline of Final Research Achievements |
We studied self-organization behaviors of spherical patchy colloidal particles, whose patches bond each other by the sticky interaction between them. We have revealed their unique self-organized structures in experiment and numerical simulation; the structures are different from those observed in conventional colloidal systems. In particular, followings were realized for the first time in this project: We (i) established the experimental system where the anisotropic interaction between patchy particles can be continuously controlled, and (ii) realized the systematic control over mesoscopic structures formed by the purely orientational order in patchy particles. Our study clarified the fundamental aspects of collective behaviors in anisotropic colloidal particles, which have attracted attentions of researchers recently. In addition, the patchy particle system would be a new mesostructured material and applied to a broad range of nano- and microsystems.
