We successfully synthesized the PVC-g-P([Ebim][Tf2N]) by utilizing ATRP reaction for the preparation of polymer/Cu nanocomposite. When Cu flakes were stirred in PVC-g-P([Ebim][Tf2N]) without any additives, Cu nanoparticles were stably generated to form the polymer/Cu nanocomposite. These dissociations of nanoparticles from flakes were attributable to the strong interaction between anions of PVC-g-P([Ebim][Tf2N]) and surface of metal. The generated Cu nanoparticles showed the polydisperse distribution, confirmed by UV-vis spectral analysis and transmission electron microscopy (TEM) imaging. Furthermore, the surface state of Cu nanoparticles was investigated by X-ray photoelectron spectroscopy (XPS), which was confirmed as the increase of binding energy. |
