| Outline of Final Research Achievements |
Monodisperse polystyrene particles, swollen by a small amount of THF in water, were pressed by a magnetic stirrer bar, so that monodisperse disc-type polystyrene particles were produced by pressing monodisperse polystyrene particles, swollen by a small amount of THF in water, using a magnetic stirrer bar. The discs were coated with a silica layer by the sol-gel reaction with tetraethoxysilane, and were further surface-treated with a silane-coupling agent having an ATRP-initiating site. Surface-initiated ATRP of methyl methacrylate (MMA) were carried out on the initiator-modified disc particles. The polymerization proceeded in a living fashion, grafting well-defined polymer brushes with a high surface-density. The resultant hybrid particles show an excellent uniformity and dispersibility, and formed a beautiful two-dimensional array on water surface, placing their planar surfaces parallel to water one.
