摘要：
Polypyrrole (PPy) nanotubes and nanowires were synthesized through electro-chemical polymerization method in nanoporous anodisc aluminum oxide (Al2O3) template. The electrolyte consisted of pyrrole monomers, solvent, and ionic liquid dopant such as BMIMPF6(1-butyl-3-methyl imidazolium tetra-fluoroborate) or BMIMPF6(1-butyl-3-methyl imidazolium hexafluorophosphate), which is stable 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 structural properties of the systems. We compare electrical properties of nano size PPy materials with bulky PPy ones prepared in the same chemical conditions.
