Nanotube Composites Consisting of Metal Nanoparticles and Polythiophene from Electropolymerization of Terthiophene-Functionalized Metal (Au, Pd) Nanoparticles

摘要

In recent years, nanostructured materials such as carbon nano-tubes, polymer nanotubes, metal nanotubes, and metal nanoparticles have received a great deal of attention due to their unique physical and chemical properties as well as their enormous potential applications such as catalysts, nanoelectronic devices, magnetic devices, sensors, and biomaterial separation membranes. It is advantageous or required to modify their nanotubes by physical or chemical methods to optimize their use in many applications. Although several methods have been developed to functionalize carbon nanotubes with inorganic and organic materials, related works on polymer nanotubes and metal nanotubes have been reported in only a few cases. Polymer nanotubes of thiophene, pyrrole, and aniline have been prepared by their electrochemical and chemical oxidations in a nanoporous alumina membrane as a template.
