Conducting Polymer Nanotube and Nanowire Synthesized by Using Nanoporous Template: Synthesis, Characteristics, and Applications

摘要

We synthesized nanotubes and nanowires of conducting polypyrrole, poly(3,4-ethylenedioxythiophene), and polyaniline by using nanoporous template through electrochemical polymerization method. The DBSA, CSA, TBAPF_6, or HClO_4 was used for dopant, and distilled water, acetonotrile, or NMP was used for solvent. From the SEM and TEM pictures, the formation f conducting polymer nanotube (CPNT) and nanowire (CPNW) was confirmed. The diameter and length of CPNT and CPNW were approx 200 nm and 10 approx 40 mum. The length, nanotube, ananowire, and thickness of wall were determined from synthetic conditions such as polymerization time, current, and dopant. For structure, we investigated UV/Vis absorbance spectra and X-ray diffraction patterns. DC conductivity and I-V characteristic curve wee measured for the systems prepared with various conditions of synthesis. For applications for CPNT and CPNW, we measured field emission characteristic curve for FED and capacitance.
