HNIW嵌入大孔纤维膜的新结构含能复合物的制备（英）

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.

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

To meet the demand of high ignition energy in narrow space,a new energetic composite was prepared compounding high-energy Hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane(HNIW) into macroporous polyacrylonitrile(PAN) fibrosa by electrostatic spinning (ES) method and self-assembly 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.
