Title：Al / CuO nanowires composite Energetic Materials and electro-explosive performance
Abstract
In the dissertation, CuO nanowires were successfully synthesized by thermal annealing of copper thin films which deposited by Magnetron sputtering on silicon substrate. The effects of different parameters, namely, film thickness, annealing temperature and annealing time on the fabrication of the CuO nanowires were investigated by FESEM, and on the average length, diameter and density of CuO nanowires. In summary, film thickness, annealing temperature, and annealing time would be set to 3.27 μm, 400 ℃, and 5 h, respectively, in order to get uniform and large-area nanowires.
XRD was applied to analyze the constitution of nanowires. The by XRD patterns showed that Cu2O and CuO were formed in annealing.
The CuO nanowires cores were served as templates for the deposition of Al shells by subsequent magnetron sputtering to get the CuO/Al core/shell nanowires. The electrical explosion experiments of the composite bridge film were implemented at triggering constant voltage of 120 V and the results showed that delay time was 16μs accompanying with duration of 1.3ms.
Key words: magnetron sputtering Al/ CuO, CuO nanowires, Characteristics of electrical explosions.
