A foolproof method for phase transfer of metal nanoparticles via centrifugation |
초록 |
Metal nanoparticles have attracted considerable attention from many researchers due to their plasmonic properties. The syntheses of metal nanoparticles have been mostly done in aqueous systems because significant effort has been already devoted to control the shape of the metal nanoparticles in aqueous systems. However, metal nanoparticles need to be dispersed in organic solvents. One of the most important reasons is the low interfacial energies in nonpolar solvents to facilitate control over nanoparticles during processing. In this paper, our new approach using centrifugal force provides a simple and foolproof method for the phase transfer of metal nanoparticles to organic solvents. The results indicate that this phase transfer method is versatile regardless of the metal species, size and shape of metal nanoparticles and ionic environment. The proposed method is more time-efficient for denser or larger nanoparticles because of the centrifugal force. Our method will help researchers to easily obtain shape-controlled metal nanoparticles dispersed finally in organic solvent systems. |
