In this paper, preparation and characterization of a copper azide nanowire array were performed. Cu nanowire arrays were previously fabricated within the pores of porous anodic aluminum oxide (AAO) template by a direct voltage electrodeposition method at room temperature. Then the AAO template was dissolved in a 1 M NaOH solution for 30 min and carefully rinsed with deionized water. The available Cu nanowires were then in-situ reacted with HN3, which was produced by heating stearic acid and NaN3, for 10-20 h and Cu nanowires were transformed into copper azide, maintaining an ordered and oriented nanostructure. The copper azide nanostructure was characterized by SEM and XRD, and DSC Was used to study the thermal decomposition of the copper azide. (C) 2012 Elsevier B.V. All rights reserved.
