Synthesis and Study of the Antimicrobial Activity of Modified Polyvinyl Alcohol Films Incorporated with Silver Nanoparticles

A new class of biologically active nanocomposites and modified polymers based on poly (vinyl alcohol) (PVA) with some organic compounds [II, IV, V VI] were synthesized using silver nanoparticles (Ag-NPs). All nucleophilic substitution interactions characterized by FTIR, DSC TGA. The biological activity the was evaluated against: gram (+) (staphylococcus aureus) (-): (Es cherichia coli bacteria). Antimicrobial films are developed MPVA Ag-NPs nanoparticles. showed better antibacterial activities against Escherichia (Gram negative) than Staphylococcus aureus positive). This work also studied effect different amounts effectiveness bacteria it found that nanocomposite (P2/Ag 5%) has superior properties coli.
