Nanocables prepared from polyamide 66 nanotubes enveloping Pt nanowires by: A secondary-template method

Abstract

Polyamide 66 (PA66) nanotubes were prepared by filtrating a PA66 solution into pores of anodic aluminum oxide (AAO) template. The AAO/PA66 nanotubes composite membrane can be used as a secondary template. Pt nanowires were then fabricated in the polymer nanotubes of the secondary template by electrochemical deposition method. Nanocables from Polyamide 66 nanotubes embedded Pt nanowires were successfully obtained. Scanning electron microscopy (SEM) and Transmission electron microscope (TEM) were employed to characterize the structure and morphology of one-dimension nanomaterials. We find that the polymer nanotubes enveloping Pt nanowires have a higher thermal-decomposition temperature than the bulk counterpart. The unique property will be beneficial to their application under a higher temperature. © 2007 The Society of Polymer Science.
