以FeCl3·6H2 O为前驱物，N，N-二甲基甲酰胺为溶剂，1，2-环氧丙烷为凝胶促进剂，采用溶胶-凝胶法制备RDX/Fe2 O3湿凝胶，利用超临界CO2萃取干燥法得到纳米复合含能材料RDX/Fe2 O3。利用SEM、FTIR、DSC等对样品的微观形貌、组分结构和热分解特性进行了研究，并测试了其撞击感度和摩擦感度。结果表明，与传统的简单混合物RDX-Fe2 O3相比，运用该方法制备的RDX/Fe2 O3纳米复合含能材料可在纳米级上将2种物质混合，其组分一致性更好；纳米复合含能材料RDX/Fe2 O3的热分解过程与 RDX-Fe2 O3不同，其 DSC曲线上的熔解吸热峰消失，分解放热峰的起始温度提前了近20℃，放热量由1082．33 J/g提高到了2129．02 J/g；纳米复合含能材料RDX/Fe2 O3的撞击感度和摩擦感度均比纯RDX及RDX-Fe2 O3钝感。

The wet gel of RDX/Fe2 O3 was prepared by sol-gel process,using FeCl3 ·6H2 O as the precursors,N,N-DMF as the solvent for FeCl3·6H2O and RDX,1,2-epoxypropane as gelating agent.The nano-composite energetic material RDX/Fe2O3 was ob-tained with supercritical extraction of the solvent in wet gel.The sample was characterized by SEM,FTIR,and DSC.Meanwhile,im-pact sensitivity and friction sensitivity were tested. Results show that the sample prepared by this method is more homogeneous in which the components are mixed in nano-level than the traditional RDX-Fe2O3.The thermal decomposition process of RDX/Fe2O3 is different from RDX-Fe2 O3 ,which the endothermic peak vanishes away from the DSC curve,the onset point of exothermic peak in-creases by 20 ℃ approximately,and the total heat release increases from 1 082.33 J/g to 2 129.02 J/g.The impact sensitivity and friction sensitivity of RDX/Fe2 O3 are more insensitive than pure RDX and RDX-Fe2 O3 .
