Abstract

This study reports the green synthesis of polymer blend nanocomposites of Polyvinyl alcohol (PVA) and Poly vinylpyrrolidone (PVP) embedded with Silver (Ag), Copper (Cu) mono metallic and Silver-Copper (Ag-Cu) bimetallic nanoparticles (NPs), generated using plant mediated solution casting method. The formation of blend, polymer-polymer interactions, interaction between polymer and nanoparticles and role of the nanoparticles on the interactions among PVA/PVP blend nanocomposites were studies by FTIR spectroscopy. The crystallinity of the prepared nanocomposites was studied by the XRD characterisation technique and it is observed that there is an increase in amorphous nature, which is due to the addition of nanoparticles into the base matrix. These green composites are suitable for various applications such as food, medical packaging and electronic industries.
