“…Polymers are interesting host matrices for embedding metal NPs as they act as reducing and capping agents and, additionally, provide environmental and chemical stability [71,72]. So, metal-polymer nanocomposites often exhibit improved optical, electrical, thermal and mechanical properties (with respect to those of the single components) [73,74].…”

Abstract:In this review, we discuss the basic concepts related to (co-)evaporation and (co)sputtering based fabrication methods and the electrical properties of polymer-metal nanocomposite films. Within the organic-inorganic hybrid nanocomposites research framework, the field related to metal-polymer nanocomposites is attracting much interest. In fact, it is opening pathways for engineering flexible composites that exhibit advantageous electrical, optical, or mechanical properties. The metal-polymer nanocomposites research field is, now, a wide, complex, and important part of the nanotechnology revolution. So, with this review we aim, starting from the discussion of specific cases, to focus our attention on the basic microscopic mechanisms and processes and the general concepts suitable for the interpretation of material properties and structure-property correlations. The review aims, in addition, to provide a comprehensive schematization of the main technological applications currently in development worldwide.

“…The wide range of PVA applications can be even more extended by incorporation of filler into PVA matrix, because well-dispersed filler may enhance various physical properties of the host polymer [9]. Since PVA can effectively protect the NPs from aggregation [10,11], numerous reports in the literature show attempts for synthesis and characterization of different NPs doped in PVA film [12][13][14][15][16][17]. The characteristics of these nanocomposite films can be manipulated by varying the particle size, shape, and concentration of NPs.…”

Polymer nanocomposite based on polyvinyl alcohol (PVA) and lead sulfide (PbS) in the average radius of (1.88-2.23) nm, have been synthesized using the chemical reduction rote and solution casting technique for different concentrations of PbS. The characterization of the polymer nanocomposite films were carried out using UVvisible spectroscopy, SEM, and XRD. The effect of various concentration of PbS NP on the optical properties of the composite has been studied to understand the optimum conditions for the synthesis process. The nanocomposite film shows high UV and visible light absorptions in the wavelength range of (200-500) nm, which correspond to the characteristics of the PbS NPs. The significant decreasing trend of the direct allowed band gap of the nanocomposite was observed upon increasing the Pb source concentration, from (6.27 eV) for pure PVA to (2.34 eV) for 0.04 M PbS concentration, which is much higher than the energy gap of bulk PbS value (0.41 eV). The calculated values of the static refractive index of Cauchy dispersion model were in the range of (1.09-1.20).X-ray diffraction analysis confirmed the cubic nanocrystalline PbS phase formation.
