CL-20/GO纳米复合含能材料的制备与性能研究

以多层氧化石墨烯为原料,高能炸药六硝基六氮杂异伍兹烷(CL-20)为填料,采用超声吸入法制备了CL-20/GO的纳米复合含能材料。利用TEM、DSC-TG、XRD对制备的样品进行了表征;并对制备的样品进行了光点火实验。结果表明:采用实验方法制备出了CL-20/GO纳米复合含能材料,证实了GO片层内部和片层上的负载物质为CL-20晶粒,负载部位在GO的片层内和片层上,呈晶粒状,清晰可见,分布较分散,无团聚,粒子大小主要集中在10~20 nm范围内,个别粒子尺寸较大,约40 nm;CL-20/GO纳米复合含能材料的起始分解温度、分解峰值温度较纯CL-20均有所提前;CL-20/SMWNTs光敏感性强,50 W的激光能量就可以将其点燃。

Preparation and Thermal Properties of CL-20/GO Nano-composite Energetic Materials

Graphene oxide (GO) were used as raw materials, and high energy explosives were used as fillings to prepare CL-20/GO nano-composite energetic materials with the method of ultrasound inhalation. Characteristics of the prepared materials were determined by using TEM, DSC-TG, and XRD, and laser ignition test was conducted. Results show that it is with this method that CL-20/GO nano-composite energetic materials were prepared. It was also demonstrated that the fillings are CL-20 grains, the filling position is on the lamela and within the layers, clear and visible, the distribution is more dispersed, no agglomeration, particle size is mainly concentrated in the 10-20nm range, the size of individual particles is about 40nm. Initial decomposition temperature and decomposition peak temperature is lower for CL-20/GO nano-composite energetic materials than for pure CL-20. CL-20/GO are characterized by high photosensitivity and laser energy of 50W can ignite them.
