PVP stabilized Silver nanoparticles were synthesized and were used to prepare different compositions of polymer nanocomposites using poly (vinyl alcohol) as a polymer matrix. AC impedance spectroscopy, tensile testing (tensile strength, Young's modulus, elongation at break), atomic force microscopy (AFM), X-Ray diffraction (XRD), Thermogravimetric analysis (TGA/DTA) and Scanning Electron Microscopy (SEM) were used to characterize the prepared nanocomposite samples. Through this communication, we are reporting a much-enhanced electrical conductivity and mechanical properties of the nanocomposite films. The AFM and SEM propose a smooth surface morphology with uniformly dispersed nanoparticles. A fairly controlled size and uniform morphology discloses that PVP has played its role in controlling the diameter and dispensability of the nanoparticles. The outcome of the XRD suggests a semi crystalline structure of XRD results suggest that the prepared nanocomposite exhibits the semicrystalline nature. Thermal analysis depicts that the thermal stability enhances as a function of the silver nanoparticles. (C) 2020 Elsevier Ltd. All rights reserved.
