Arsenic Antibacterial Polymer Composites Based on Poly(Vinyl Chloride)

摘要

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).
