摘要:
利用模板法在硅基上制备了一种新型的Al/Ni纳米复合含能材料，利用场发射扫描电镜(FESEM)和X射线能谱衍射(EDS)分别对其进行了形貌表征和元素分析，采用差示扫描量热法(DSC)对该材料的热反应性能进行了检测，并通过脉冲激光对复合材料的激光点火性能进行了初步研究。结果表明：该复合材料具有嵌入式的纳米结构，该结构大大增加了反应物的接触面积，而且表现出较高的热反应活性；激光点火后，存在着较长时间的火花抛洒，对实际起爆过程十分有利，该纳米复合含能材料50%发火的激光能量约为36.28 mJ (能量密度为46.22 mJ/mm2)。
Abstract:
A new nanostructured Al/Ni energetic composite was prepared on silicon (Si) substrate using template method. Field emission scanning electron microscopy (FESEM) and energy dispersive X-ray spectra (EDS) were employed to observe the morphology and characterize the compositional properties of Al/Ni energetic nanocomposite, respectively. The thermal reactivity of Al/Ni energetic nanocomposite was determined by a differential scanning calorimetry (DSC). Moreover, ignition of nanocomposite was examined by a single pulsed laser irradiation. The results showed that the portion of nickel (Ni) nanorods is embedded in the aluminiun (Al) film, which results in a larger physical contact between Al and Ni and a corresponding higher thermal reactivity of Al/Ni. After being ignited, it produces sparks lasting for several milliseconds, which is advantageous to its explosion application. The 50% firing energy of the Al/Ni energetic composite is about 36.28 mJ , with an energy density of about 46.22 mJ/mm2.
