Outline of Final Research Achievements

Seeded dispersion polymerization of ionic liquid monomer was carried out in the presence of poly(methylmethacrylate) (PMMA) as seed and composite particles with poly(ionic liquid) (PIL) were obtained. Moreover, we showed that anion exchange of the composite particles can be used to modify the properties of only the PIL component of the composite particles. PIL particles with a single-hollow are also prepared by suspension polymerization from monomer droplets consisting of the ionic liquid monomer, ethylene glycol dimethacrylate, and n-butyl acetate. The obtained particles can be changed from hydrophobic to hydrophilic by anion exchange. Moreover, Janus particles with two hemispheres having different stabilizers, a polystyrene (PS) phase stabilized by poly(acrylic acid) and a PMMA phase stabilized by poly(vinyl pyrrolidone), were able to be synthesized. The facile formation of the colloidal chains via hydrogen bonding interaction between different stabilizers were demonstrated.
