Ag nanoparticles supported within polyvinyl alcohol (PVA)/polyvinyl pyrrolidone (PVP) films have been successfully synthesized using novel in situ method. PVA and PVP acted as stabilizer and polyol reductant, respectively. The successful incorporation of silver nanoparticles in PVA/PVP matrix was confirmed by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscope (TEM) and Fourier transform infrared (FTIR) spectroscopy. It was found that PVA/PVP-stabilized silver nanocomposite film revealed the presence of well-dispersed and spherical silver nanoparticles with an average diameter of 30 nm, while the particle sizes were reduced as the PVP percentage increased. A possible formation mechanism of Ag nanoparticles is also proposed in this article. (C) 2012 Elsevier B.V. All rights reserved.
