以含能聚合物(EP)和硝基胍(NQ)为原料,采用溶剂/非溶剂法制备了EP/NQ复合含能材料,采用扫描电镜(SEM)、比表面积测试法(BET)和X射线衍射(XRD)对其形貌和结构进行了表征,用热重-差示扫描量热法(TGDSC)对比分析了EP/NQ复合含能材料及其物理共混物的热性能。结果表明,EP/NQ复合含能材料具有三维纳米网络结构,NQ沉积在EP上面,其平均粒径为49~62 nm,NQ的长针状结晶消除;与EP相比,EP/NQ复合含能材料的比表面积降低,且随着NQ质量分数由40%增至60%,EP/NQ复合含能材料的比表面积由54.599 m~2/g降至25.02 m~2/g;EP/NQ复合含能材料具有单一的热分解峰特性,热分解峰温比NQ提前55~59℃,且随着NQ质量分数由40%增至60%,EP/NQ复合含能材料的热分解峰温由200.1℃升至203.7℃;EP/NQ复合含能材料的分解热显著高于EP/NQ物理共混物。 |

Energetic Polymer/Nitroguanidine composite energetic material was prepared by solvent/non-solvent method using energetic polymer(EP)and nitroguanidine(NQ)as raw materials.Its morphology and structure were characterized by scanning electron microscope(SEM),BET method and X-ray diffraction (XRD).The thermal properties of EP/NQ composite energetic material and its physical blends were compared and analyzed by thermogravimetry- differential scanning calorimetry(TG-DSC).Results show that the EP/NQ composite energetic material has a three-dimensional nano-network structure.The NQ particles with mean particle size of 49-62 nm are deposited on EP and the long needle-like form of NQ is eliminated.The surface area of EP/NQ composite energetic material is smaller than that of EP,and the surface area decreases from 54.599 m~2/g to 25.02 m~2/g with increasing the mass fraction of NQ from 40%to 60%.EP/NQ composite energetic material has the characteristic of a single thermal decomposition peak,its thermal decomposition peak temperature is 55-59℃lower than that of NQ and its peak temperature rises from 200.1℃to 203.7℃ with increasing the mass fraction of NQ from 40%to 60%.The decomposition heat of EP/NQ composite energetic material is much higher than that of the physical blends. |
