Paper Title:
Size-Controlled Synthesis of Hyperbranched Polymer Protected Gold Nanoparticles
  Abstract

Gold nanoparticles dispersions were prepared by hyperbranched polyamide (HB-PA) in aqueous solution without additional reducing agents. The prepared gold nanoparticles/polymer composites were characterized by UV-visible spectrophotometer, TEM and HPPS. The size of the synthesized gold nanoparticles decreases with the increase of the molar ratio of nitrogen in HB-PA to Au atoms. EDS, XRD as well as XPS were further employed to verify these particles were indeed metallic gold nanoparticles and FT-IR analysis showed the interaction between gold nanoparticles and polymers. These techniques indicated the tunability of the size of gold nanoparticles by HB-PA which can also serves as a layer of protection for them.
