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。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.
