Arsenic Antibacterial Polymer Composites Based on Poly(Vinyl Chloride)

Abstract

Summary New compositions based on arsenic oxide nanoparticles and poly(vinyl chloride) (PVC) were prepared. Sufficient antibacterial activity has been achieved for Escherichia coli and Pseudomonas syringae. The antibacterial materials so obtained are non‐irritant. At the same time, the PVC‐based composites have high thermal stability as demonstrated by thermogravimetric analysis and aging of samples; crosslinking enhances thermal stability. Still further, we have determined scratch resistance in a microscratch tester. High scratch resistance has been demonstrated, including strong viscoelastic scratch recovery (the bottom of the groove goes up inside of 2 minutes).

“…The antibacterial activities of porous scaffolds against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) were evaluated via the inhibition zone method. 54,55 First, the bacterial suspensions were dispersed in the aseptic broth medium, and the bacterial concentration was about 10 7 CFU mL À1 . Second, 0.6 mL of the inoculation bacterial suspensions were spread on the nutrient agar plates uniformly.…”

“…One of the primary reasons to conduct the present work is the easy availability of As 2 O 3 in the Republic of Georgia 9, 10 while these oxides are known to exhibit also anti-cancerous properties [11][12][13] . The potential benefit of arsenic as an antibacterial agent was recognized when As 2 O 3 was added in small concentrations to poly(vinyl chloride) 14 . Sufficient antibacterial activity has been achieved when tested in E. coli and P. syringae media 14 .…”

“…The potential benefit of arsenic as an antibacterial agent was recognized when As 2 O 3 was added in small concentrations to poly(vinyl chloride) 14 . Sufficient antibacterial activity has been achieved when tested in E. coli and P. syringae media 14 . We explore the antibacterial properties of As 2 O 3 when added to a widely used polymer, namely poly(vinyl chloride) (PVC), and comparing it to a known antimicrobial agent, Ag 2 O.…”
