| Outline of Final Research Achievements |
It was recently discovered that sputter deposition of Au onto the surface of a luquid poly(ethylene glycol) (PEG) generates Au nanoparticles (NPs) in the liquid with no additional stabilizing agents. To further control the size and shape of Au NPs, the method was improved in the present study by adding ionic liquids as stabilizing agents to PEG. The synthesized Au NPs were structurally characterized and the results were compared with earlier findings of Au NPs prepared in neat ionic liquids and neat PEG. The Au NPs prepared with the addition of ionic liquids were spherical. The size and size distribution of Au NPs differ greatly, depending on the concentration of ionic liquid and type of constituent anion of ionic liquids used as stabilizing agent. This study indicates that the size of Au NPs prepared in PEG can be controlled by adding a small amount of ionic liquids.
