摘　　要：以开口多壁碳纳米管(SMWNTs)为原料,六硝基六氮杂异伍兹烷(CL-20)为填料,采用超声吸入法制备CL-20/SMWNTs纳米复合含能材料;利用TEM、DSC-TG、XRD对样品进行表征,并对其进行激光点火试验。结果表明,CL-20晶粒填充到SMWNTs内部,填充部位在SMWNTs的端口,呈颗粒状排列。与纯CL-20相比,CL-20/SMWNTs纳米复合含能材料的起始分解温度由原来的239.6℃降至229.6℃,分解峰温也由原来的221.4℃降至173.6℃。CL-20/SMWNTs纳米复合含能材料光敏感性强,激光能量50W时可将其点燃。The hexanitrohexaazaisowurtzitane(CL-20)/split multi-walled carbon nanotubes(SMWNTs)nano-composite energetic material was prepared by an ultrasound inhalation method using SMWNTs as raw material and CL-20 as filler.It was characterized by TEM,DSC-TG and XRD and laser ignition test was conducted.The results show that CL-20 grains are filled into the SWMNTs,and the filling position is at the port of SWMNTs,which is arranged with granular.Compared with pure CL-20,the initial decomposition temperature of CL-20/SMWNTs decreases from 239.6℃to 229.6℃,and the peak temperature reduces from 221.4℃ to 173.6℃.CL-20/SMWNTs nano-composite energetic material has high photosensitivity and can be ignited under laser energy of 50 W.
