摘要:本论文在Si基底上利用磁控溅射沉积的Cu膜为样品,通过热退火制备CuO纳米线。通过FE-SEM表征手段研究Cu膜厚度、热退火时间和热退火温度对纳米线生长的影响以及对纳米线长度、直径和密度的影响。结果表明当铜膜厚度为3.27um,热退火温度为400℃时,保温5小时条件下,Cu膜的表面覆盖有大面积的纳米线,8471
通过XRD对纳米线进行结构表征,结果表明XRD分析表明热退火后的Cu膜表面含有Cu2O和CuO两种物质。
利用磁控溅射在CuO纳米线上沉积Al膜形成具有核-壳结构的CuO纳米线/Al复合纳米含能材料。将此纳米含能材料制备为点火桥膜,测其在恒压为120V触发下,起爆延迟时间为16μs,起爆持续时间为1.3ms。

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.
