| 摘 要： | 以含能聚合物(EP)为基底通过共沉淀法制备了奥克托今(HMX)/高氯酸铵(AP)/含能聚合物(EP)纳米复合物。用扫描电镜(SEM),能量色散X射线能谱(EDS)、比表面积(Brunauer-Emmett-Teller(BET))测定、红外(IR)光谱法和差示扫描量热法(DSC)表征了它的结构及性能。结果表明,HMX/AP/EP纳米复合物具有三维纳米网状结构。HMX和AP均匀沉积在EP上面,其尺寸为50~200 nm。HMX、AP和EP紧密结合在一起,具有良好的相容性。HMX/AP/EP纳米复合物的分解温度远低于HMX的。当HMX/AP/EP纳米复合物的氧平衡为零时,其分解热高达2570 J·g-1。HMX/AP/EP纳米复合物的撞击特性落高H50为50.49 cm,与HMX的撞击感度的特性落高(27 cm)相比,其机械感度较低。

| Abstract: | The cyclotetramethylene tetranitramine (HMX)/ammonium perchlorate (AP)/energetic polymer (EP) nanocomposite was prepared by a co-precipitation method using a novel EP as matrix. Its structure and properties were characterized by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), specific surface area (Brunauer-Emmett-Teller (BET)) measurement, Infrared (IR) spectrometry, and differential scanning calorimetry (DSC). Results show that the HMX/AP/EP nanocomposite possesses the three-dimensional nano-network structure. The HMX and AP particles are uniformly deposited on EP, whose size is in the range of 50-200 nm. HMX, AP and EP are closely bonded each other with good compatibility. The thermal decomposition temperature of the HMX/AP/EP nanocomposite is far lower than that of HMX. When the oxygen balance of HMX/AP/EP nanocomposite is zero, its decomposition heat is up to 2570 J·g-1.Compared with the characteristic drop height of impact sensitivity (H50) of 27 cm of HMX, the value of H50 of the HMX/AP/EP nanocomposite is 50.49 cm, revealing that the latter has lower mechanical sensitivity. |
