| 제목 | Synthesis of Magnetite-Block Copolymer Nanoparticle Composites |
| 초록 | Magnetite and block polymer (PHEMA-b-PMMA) nanocomposite was synthesized by ATRP in an ionic liquid. Magnetite nanoparticles were firstly surface-modified with an initiator under DMF (dimethylformamide) solvent, which produced the macro-initiator Fe3O4–init which initiated the polymerization for synthesis of block polymer. After immobilization of the initiator on surface of Fe3O4, block polymer chains were grafted successfully onto the surface of Fe3O4, causing to the formation of core-shell nanostructure. The incorporation of Fe3O4 in the nano-composite was confirmed by FT-IR, XRD, TEM, NMR and XPS. This method can provide a green synthetic route that has advantages over conventional methods, such as easy separation, fast removal, and convenient recovery of solvent.
