N2  - Doped and de-doped nanotubes and nanowires of polypyrrole, polyaniline, and poly(3,4-ethylenedioxythiophene)were synthesized by the electrochemical polymerization method, using Al2O3 nanoporous templates. The electrical and optical properties of the nanotubes and nanowires were controlled through various synthetic conditions, such as doping level, dopant, and template-dissolving solvents. The diameters and wall thicknesses of the nanotubes were 100-200 nm and 10-30 nm, respectively. To determine the electrical and optical properties of the nano-systems, I-V characteristic curves with gate bias, dc conductivity, and UV-vis spectra were measured. We observed that the nanosystems were transformed from a conducting state to a semiconducting (or insulating)state through the process of de-doping using the template-dissolving solvents. Possible applications of these nanotubes and nanowires in the construction of nanotip emitters in field emission displays and polymer-based transistors are presented
