摘要:首次用溶胶-凝胶(sol-gel)方法成功制备了HMX/AP/RF纳米复合含能材料。采用SEM扫描电镜、BET比表面积分析、XRD粉末衍射和DSC差示扫描量热法对复合材料的结构进行表征。结果表明:HMX/AP/RF气凝胶具有纳米网孔结构,比表面积为27.13m2/g ,相比空白RF气凝胶明显下降;HMX/AP/RF气凝胶中晶体的平均晶粒度为48~93nm,HMX/AP/RF气凝胶的热分解峰较原物质HMX相比有所提前。
Abstract:HMX/AP/RF aerogel was prepared by sol-gel method, and its structure was characterized by SEM、BET、XRD and DSC. The results showed that HMX/AP/RF aerogel has nano-grid structure. The surface area of HMX/AP/RF is 27.13m2/g and much smaller than RF aerogel. The mean crystal size of HMX/AP/RF aerogel is from 48nm to 93nm. Compared to HMX, the thermal decomposition temperature of HMX/AP/RF aerogel is decreased.
