两种不同结构纳米叠氮化铜的含能特性研究

摘要

针对两种不同结构纳米叠氮化铜(三维多孔结构以及一维阵列结构)开展含能特性研究,重点研究了热性能以及电爆性能.研究结果表明:叠氮化铜的不同纳米结构影响其热性能及电爆性能.当采用镍铬换能元起爆叠氮化铜时,相比于三维多孔结构叠氮化铜,一维阵列结构叠氮化铜对热更敏感,同时可以释放出更多能量.当采用半导体桥换能元起爆叠氮化铜时,不同于三维多孔结构叠氮化铜的热引发机理,一维阵列结构叠氮化铜的50%发火电压更大,作用时间更长,引发机理为等离子引发.%Aimed at 3D porous structure and 1D nanowire structure copper azide, thermal behavior and explosion performance was studied. Results show that the different nano-structure of copper azide has certain effect on thermal properties and explosion properties. When the copper azide was ignited by Ni-Cr micro-initiator, 1D nanowire structure copper azide is more sensitive to heat, and can release more energy than that of 3D porous structure copper azide, while the copper azide was ignited by semi-conductor bridge, the 50% firing voltage of 1D nanowire structure copper azide is higher, as well as the function time is longer, which show that the firing mechanism is plasma ignition, and different to heat ignition mechanism of 3D porous structure copper azide.
