Colloidal Polymerization of Dipolar Nanoparticles: A New Concept in Polymer Science |
| 초록 |
Ferromagnetic nanoparticles represent an intriguing class of nanocomposite colloids capable of self- assembly via spin dipolar interactions. We will discuss our recent efforts for the synthesis, functionalization and assembly of polymer coated ferromagnetic nanoparticles based on metallic cobalt. We have recently extended the utility of dipolar NP assembly to prepare mesoscopic polymers composed of semiconductor metal oxide and heterostructured nanowires. A novel synthetic methodology, termed, “Colloidal Polymerization” has been developed where dipolar cobalt nanoparticles were used as “colloidal monomers” to form fused 1-D nanomaterials of cobalt oxide. Using a combination of magnetic assembly and a wide range of chemical reactions (e.g., oxidation, galvanic exchange), cobalt oxide nanowires with controlled placement of noble metal inclusions has been achieved. The synthesis and characterization of these materials will also be discussed |
