| Outline of Final Research Achievements |
The purpose of this study is to systematically investigate the dispersibility and arrangement behavior of polymer-brush-decorated hybrid particles in liquid crystals, and to develop a novel colloid/liquid-crystal dispersion system that is attracting attention both academically and practically. We here have developed a technology that can control the orientation behavior of liquid crystals to a surface by the type of polymer brush grafted on fine particles. It should be noted that we could found disclination structures such as hexadecapolar and baseball types, which are rarely reported. In addition, we succeeded in expanding this technique into rod-shaped particles and found the orientation behavior of liquid crystal peculiar to anisotropic fine particles. Furthermore, we clarified that the arrangement state of fine particles in the liquid crystal can be controlled by appropriately selecting polymer brush grated on the surfaces.
