Outline of Final Research Achievements

The structures containing 2D or 3D ordering of nano/micrometer-sized monodisperse particles have several key applications in materials science and engineering. The study on the geometrical packing / arrangement of such particles has been proposed and developed for fabricating colloidal crystals with 2D or 3D ordered structures.
However, localized ordering of particles occurs in limited areas, leading to the aggregate containing spatially partitioned domain structures with anisotropic orientations. In order to overcome such a difficulty, the application of external fields such as mechanical and electrical fields to fabricate 2D or 3D close-packed structures was examined for composite spherical silica particles in this study.
