HNIW嵌入大孔纤维膜的新结构含能复合物的制备（英文）

Preparation of New Structure Energetic Composite of HNIW Implanted into Macroporous Fibosa

为了满足狭窄空间高点火能量的需要,利用静电纺丝法和自组装法将高能的六硝基六氮杂异伍兹烷(HNIW)复合到大孔聚丙烯腈(PAN)纤维膜中制备了一种新的含能复合物。用扫描电镜、红外、热分析和燃烧残渣分析了其形貌、热性能和燃烧行为。结果表明,HNIW均匀分布在纤维膜上。二者的复合是物理过程,没有化学变化。与单纯PAN纤维膜相比,HNIW的加入增强了纤维膜的燃烧性能,并且HNIW的起始放热点也因为纤维的存在而提前38℃。在特定比例下纤维和HNIW可以完全反应。

To meet the demand of high ignition energy in narrow space, a new energetic composite was prepared compounding high-energy Hexanitro-2,4,6,8,1 0,1 2-hexaazaisowurtzitane（HNIW） into macroporous polyacrylonitrile（PAN） fibrosa by electrostatic spinning（ES） method and selfassembly method. The morphology, thermal property and combustion behavior of as-prepared composite were analyzed by SEM, FT-IR, thermal analysis and combustion residues analysis. Results show that HNIW is uniformly distributed on the fibrosa; their compound is a physical process; there is no chemical change. Compared with pure PAN fibrosa, the addition of HNIW enhances the combustion performance of fibrosa, and initial exothermic temperature of HNIW shifts about 38 ℃ downwards because of the existence of fiber. The fiber and HNIW can completely react in a particular proportion.
