Green Synthesis of Poly(vinyl alcohol)‐Silver Nanoparticles Composite Using Kendu (Diospyros melanoxylon Roxb) Fruit Peel Extract and Its Antibacterial Activity

Abstract

AbstractGreenly synthesized silver nanoparticles (AgNPs) are gaining attention as potential antimicrobials. We report on the green method for the synthesis of poly (vinyl alcohol) (PVA) – silver nanoparticles (PVA‐AgNPs) composite 1 using Kendu (Diospyros melanoxylon Roxb) fruit peel (KFP) aqueous extract. The use of KFP extract for the synthesis of AgNPs in the composite has been investigated for the first time. UV−visible spectroscopy and transmission electron microscopy (TEM) are employed to characterize the prepared AgNPs. The FTIR and 1H NMR spectral analyses reveal the involvement of phytochemicals of the KFP extract in the composite synthesis. The composite exhibits strong antibacterial activity against both Gram‐ negative Escherichia coli and Gram‐positive Staphylococcus aureus bacterial pathogens and action increases with AgNPs content.
