Abstract
Polypyrrole/silver (PPy/Ag) nanocomposites of weight percentages (0.1%, 0.5%, 3%, 5% and 7% wt.) were synthesized via a chemical oxidation method. The AFM analysis is performed to study the surface roughness, morphology and size distribution of PPy particles and PPy-Ag nanocomposites. The results indicated that as the concentration of Ag in the nanocomposite increases, the roughness increases. The size of nanoparticles was also evaluated and found to be in the range of 15 nm to 125 nm. The PPy/Ag nanocomposites exhibited an effectiveness against Gram-negative Escherichia coli showing an inhibition zone of 4mm and displayed poor efficacy against Gram-positive Staphylococcus aureus. Based on given adequate antibacterial characteristics of PPy/Ag nanocomposites, it can be identified as a promising material in biomedical applications.
