제목 Preparation of Various Organic, Inorganic and Core-Shell NanoparticlesBy Using Monodisperse Polymer Colloids and Nanosized Iron Oxide
초록 Cationic polymeric nanospheres synthesized by emulsifier-free emulsion polymerization were used as core materials, which are subsequently treated with titania or silica inorganic precursors to form various organic core-inorganic shell hybrid nanoparticles. The hollow nanospheres were prepared by calcination at 500℃. Magnetite(α-Fe3O4) core/titania shell nanoparticles were also synthesized by layer-by-layer (LbL) self assembly method. By using a magnetite core, oppositely charged polymer and titanium precursor were alternatively deposited several times through layer-by-layer self assembly and slowly annealed at high temperature for 24 hrs in an attempt to convert from amorphous to anatase titania in the shell phase. Hollow titania and mesoporous silica nanoparticles were also prepared by monodisperse polymer colloids as a template.
