Discipline: Chemistry



Polypyrrole (PPy) nanowires were synthesized via chemical oxidation polymerization using an Anodic Aluminum Oxide (AAO) membrane template. The varied chemical polymerization parameters were (1) polymerization time, (2) Py monomer concentration, (3) FeCl3 oxidant/dopant concentration, (4) Py monomer to FeCl3 dopant concentration, and (5) polymerization temperature. The synthesized PPy nanowires were characterized through 4-point probe conductivity method, FE-SEM, and antimicrobial assays. The optimum polymerization conditions were 60 minutes polymerization time, 0.2M Py monomer, 0.4M FeCl3 oxidant/dopant, and polymerization temperature of 8±1°C.
