Synthesis of heterosegment-junctioned hybrid nanotubes of polythiophene and heterometallic nanoparticles by sequential template-based electropolymerization

摘要

New heterosegment-junctioned hybrid nanotubes of polythiophene and heterometallic nanoparticles (Pd, Au NPs) have been synthesized by sequential electropolymerization of terthiophene-modified Pd and Au NPs in a nanoporous template. One-dimensional (ID) nanomaterials, i.e., tubes, wires, and rods, and metal nanoparticles (NPs), have received considerable recent attention due to their fundamental significance and potential applications in nanoscale devices and sensors.1"7 In particular, the nanotubular structure has attracted significant interest because its wall thickness and length can be used to control the physical and chemical properties. Generally, conductive polymer nanotubes of thiophene, pyrrole, and aniline are fabricated by chemically or electrochemically using various templates.
