Abstract

Polypyrrole (PPy) nanotubes and nanowires were synthesized through electrochemical polymerizalion method in nanoporous anodisc aluminum oxide (Al₂O₃) template. The electrolyte consisted of pyrrole monomer, solvent, and ionic liquid dopant such as RMIMBF (I-butyl-a-mcthyl imidazolium letrafluoroborate) or BMIMPF (I-butyl-3-methyl imidazolium hexafluorophosphate); which is stahle in air and moisture. The length and diameter of PPy nanotubes and nanowires were determined by the synthetic conditions such as polymerization time, current, and dopant. The formation of nanotube and nanowire of PPy sample was confirmed by using field emission scanning electron microscope and transmission electron microscope. The UV/Vis and Raman spectra have been investigated for structured properties of the systems. We compare electrical properties of nano size PPy materials with bulky PPy ones prepared in the same chemical conditions.
