Outline of Final Research Achievements

We have investigated a preparation of core-shell hybrid particles by surface initiated anionic polymerization through lithiation of tolyl groups introduced at the surface of inorganic particles. Objective core-shell nanoparticles were successfully obtained by using various inorganic particles such as silica, carbon nanotubes, and metal nanoparticles. We prepared composite materials by using the surface modified silica or carbon nanotube. The obtained composites showed higher mechanical properties compare with those prepared with non-surface modified inorganic particles. Strong covalent bondings between core materials and shell polymer segments, and high dispersion behavior of the particles in the matrices might enhance the mechanical properties of the composites.
