摘　　要：叠氮化铜是一种绿色环保的高能含能材料,其极高的静电感度限制了它在MEMS火工品微型装药中的应用。碳纳米管优异的导电性可以有效地降低叠氮化铜的静电感度,而且取向一致、高机械强度的碳纳米管可以有效地提高叠氮化铜的安全性和爆轰输出能量。本文中,设计并制备了基于硅基底及多孔氧化铝模板的内嵌叠氮化铜碳纳米管复合含能材料,探究了合适的制备条件,并对样品进行了表征分析。结果表明:在氧化电压45V、沉积电流密度0.1mA/cm^2条件下制备的复合材料,经72h叠氮化反应后得到的内嵌叠氮化铜碳纳米管复合含能材料在静电感度仪测试范围(≤25kV)内均未发火,有望作为一种新型含能装药应用于MEMS器件中。Copper azide is a green and environmentally friendly energetic material, but its high electrostatic sensitivity limits its application in MEMS initiating explosive device. The excellent conductivity of carbon nanotubes can effectively reduce the electrostatic sensitivity of copper azide. Moreover, with uniform orientation and high mechanical strength, aligned carbon nanotube array can effectively improve the safety and output energy of energetic materials. A composite energetic material of carbon nanotubes embedded with copper azide based on silicon substrate and porous alumina template was designed and prepared in this paper. The suitable preparation conditions were studied, and the samples were characterized and analyzed. The results show that, as a novel energetic material, the prepared carbon nanotubes embedded with copper azide, which fabricated under 45V oxidation voltage and 0.1 mA/cm^2 deposition current density and 72 h azide reaction, exhibit low electrostatic sensitivity, and they were hardly ignited in the electrostatic sensitivity meter test voltage range (≤25kV). Therefore, this composite energetic material is expected to be applied to MEMS devices.
