Monodisperse and Size-tunable Iron Oxide Nanoparticles via Block Copolymer Self-Assembly |
| 초록 |
Size-tunable pattern transfer strategy via block copolymer lithography is demonstrated. Self-assembly of poly(stryrene-block-4-vinyl pyridine) (PS-b-P4VP) block copolymer generates vertical cylinder morphology by solvent annealing. In a weakly acidic aqueous solution, P4VP block becomes protonated and attracts the anionic metal complexes through electrostatic interaction. We can fabricate sub-nanometer level size nanoparticle array by using this method. The controlled growth of monodisperse nanoparticle array is shown by their catalytic use for vertical carbon nanotube (CNT) growth via plasma enhanced chemical deposetion (PECVD). |
