Abstract

Highly conducting poly(3,4-ethylenedioxythiophene) (PEDOT) nanotubes were fabricated by vapor deposition polymerization using anodic aluminum oxide (AAO) nanopororus template. Highly ordered PEDOT nanotube arrays with high respect ratios were produced using this process. The nanoscale diameter and microscale length of the nanotubes were controlled by the pore sizes and depths of the AAO membranes, respectively. The PEDOT nanotubes in the bulk sample had a very high conductivity of 2,000 S/cm. Raman and X-ray photoelectron spectroscopies, transmission and scanning electron microscopies, and atomic force microscopy were used to determine the structure as well as the electrical and optical properties of the PEDOT nanotubes.
