Outline of Final Research Achievements

In order to precisely synthesize disk-like particles with narrow particle size distribution of the structure, the monodispersed polystyrene spherical particles were dispersed in water containing a small amount of THF as a good solvent, and the dispersion liquid was stirred in a rotary compression apparatus. Using the obtained particles, atom transfer radical polymerization of methyl methacrylate and styrene was carried out to synthesize disc shaped particles modified with a graft polymer having a narrow molecular weight distribution. In addition, we have newly developed a route to synthesize cobalt hydroxide disk like particles grafted polymer brushes. The process of ordered formation of the hybrid particles was observed in real space using a confocal laser scanning fluorescence microscope. As a result, it was revealed that the formed ordered structure largely depends on the molecular weight of the graft polymer of the hybrid particles, that is, their aspect ratio.
