Abstract
The present research work reports the fabrication of polyvinyl alcohol (PVA) based core shell nanocomposite films by assimilation of various concentrations of Fe @ Ag core shell nanoparticles in PVA matrix. Ex-situ chemical reduction approach was used for synthesis of core shell nanoparticles in which sodium borohydride (NaBH4) and tri-sodium citrate were used as a reducing and capping agent respectively and subsequently Fe @ Ag-PVA nanocomposite films were fabricated via solution casting method. These nanocomposite films were further characterized to examine the effect of varying concentration of core shell nanoparticles on PVA matrix by using UV-Visible spectrophotometer so as to study the absorbance behavior and to calculate the electrical conductivity of core shell nanocomposite. Morphological studies of the Fe @ Ag-PVA nanocomposite films were carried out using Transmission electron microscopy (TEM).
