A Novel Approach to Prepare Poly(Vinyl Acetate)/Ag Nanocomposite for Effective Antimicrobial Coating Applications

Abstract

Polyvinyl acetate (PVAc) nanocomposites were successfully prepared based on silver nanoparticles (Ag-NPs). Firstly, Ag-NPs was directly prepared during the in situ emulsion polymerization of vinyl acetate monomer using AgNO 3 as a source of Ag + ions and poly(vinyl alcohol) (PVA) was used for dual functions as emulsifier for emulsion polymerization and a s stabilizer agent, tri-sodium citrate (C 6 H 5 O 7 Na 3 ) was used as reducing agent for Ag + ions during the polymerization process. The prepared PVAc/Ag nanocomposites were assessed using XRD, SEM, FT-IR, TEM and UV-spectra. The antibacterial properties of the prepared PVAc/Ag nanocomposites were investigated as antimicrobial activity against pathogenic bacteria, i.e., Staphylococcus aureus (G +ve bacteria) and Escherichia coli (G -ve bacteria). These PVAc nanocomposites could be used as a promising material for enhanced and continuous antibacterial applications as coating and packaging materials.

Production of Low-Cost Nano-Functionalized Bacterial Cellulose Films for Smart/Intelligent Packaging

“…Recent studies have reported the use of silver, zinc oxide, and titanium oxide NPs in the development of antibacterial nanopackaging films. However, the major drawback of this process is the migration of these nanoparticles from the packaging materials to the food samples, causing carcinogenicity [13,14].…”

Evaluation of Antioxidant Efficiency of Croton tiglium L. Seeds Extracts after Incorporating Silver Nanoparticles

“…Presence of the plant extract reduced formation of AgNO 3 into Ag ions. Moreover, the secondary metabolites present in the extract act as a reducing and a capping agent for Ag-NPs synthesis [74][75][76][77][78].…”
