以聚叠氮缩水甘油醚（GAP)和六亚甲基二异氰酸酯（HDI）为原料，二月桂酸二丁基锡（T-12）为催化剂，通过溶胶凝胶法及溶液结晶法制备了RDX/GAP纳米复合含能材料。用BET法、X-射线粉末衍射、扫描电镜对其结构进行了表征，用TG/DSC分析了其热性能。结果表明，RDX/GAP纳米复合含能材料具有纳米网孔结构，与GAP干凝胶相比，其比表面积下降，平均粒径为20～50nm。RDX/GAP纳米复合含能材料中的RDX热分解峰温明显提前，分解热显著高于RDX/GAP物理共混物的分解热。

RDX/GAP composite energetic material was prepared by sol-gel method and solution crystallization 淠攀琀栀漀搀 using glycidyl azide polymer (GAP) and hexamethylene diisocyanate(HDI) as raw materials and T-12 as catalyst. Its structure was characterized by BET method, X-ray powder diffraction and scanning electron microscopy and its thermal properties were analyzed by TG/DSC. 勠攀猀甀氀琀猀 show that RDX/GAP composite energetic material has nano-grid structure and its surface area is much smaller than that of GAP xerogel. The mean particle size of RDX/GAP composite energetic material is 20-50nm. The thermal decomposition peak temperature of RDX in the composite energetic material is greatly decreased, and the decomposition heat is much higher than that of the physical blend materials.
