The Impact of Preparation Time on AgNPs Doped PVA and Its Implication in Antimicrobial Activity
Wed Abed
Abstract:
(4952 Views)
Silver/polyvinyl alcohol (Ag/PVA) nanocomposites were fabricated via an
electrochemical method
. Silver nanoparticles (AgNPs) with varying grain sizes were directly synthesized within PVA polymer matrices at deposition times of 15, 30, 45, 60, and 120 minutes. The integration of AgNPs within the PVA matrix was confirmed through
Transmission Electron Microscopy (TEM)
and optical absorbance measurements.
X-ray Diffraction (XRD) analysis
demonstrated the face-centered cubic structure of AgNPs. Furthermore, these prepared nanocomposites
exhibited
significant
antibacterial properties against Bacillus subtilis and Pseudomonas pneumonia, as well as antifungal activity against Alternaria alternata
.
Remarkably, the
AgNPs/PVA nanocomposite
exhibited outstanding antifungal efficiency, resulting in an impressive inhibition zone of up to 47 mm.
Keywords:
Ag/PVA nanocomposite
