原位反应法制备填充叠氮化铜的碳纳米管阵列

以定向碳纳米管阵列为工作电极,采用电化学沉积法制备填充纳米铜颗粒的碳纳米管阵列,研究不同电沉积参数对碳纳米管填充铜纳米颗粒的影响规律;采用气-固原位反应法获得填充叠氮化铜的碳纳米管含能阵列。采用扫描电镜、X射线衍射仪对填充叠氮化铜的碳纳米管阵列及其前驱体进行结构表征,采用差示扫描量热仪研究其热性能。结果表明:当沉积电流为1 mA和10 mA,可获得填充效果理想的填充有纳米铜的碳纳米管阵列;气固原位反应过程中碳纳米管阵列不与叠氮酸发生反应。在热板点火作用下填充叠氮化铜的碳纳米管阵列可靠起爆。采用兰利法获得其50%电发火能量为3.09 mJ。

In-situ Preparation of Carbon Nanotubes Array Confined with Copper Azide

Carbon nanotubes (CNTs) array confined with nano copper was prepared by electrochemical deposition method with CNTs array as working electrode. The effect of electrodeposition parameters on deposition of copper nanoparticle filled on CNTs array was studied. CNTs array confined with copper azide was obtained by gas-solid in-situ reaction. Scanning electron microscope, X ray diffracmeter and differential scanning calorimetry were used to characterize the structures and thermal properties of CNTs array confined with copper azide and nano copper. Results show that CNTs array confined with nano copper can be obtained at 1 mA and 10 mA. CNTs is not react wiht HN₃ during the in-situ process. CNTs array confined with copper azide can be initiated by thermal stimulus reliably. The 50% fire energy by Langlie method is 3.09 mJ.
