摘要
超声波技术在复合含能材料制备领域具有显著优势,通过减小结晶亚稳区、缩短晶核形成时间,避免碎晶聚集,辅助高性能有机纳米共晶体制备。超声辅助乳化技术能制备微球状共晶体,提升机械感度。同时,超声技术能制备奥克托今@三氨基三硝基苯(HMX@TATB)、高氯酸铵@三氨基三硝基苯(AP@TATB)等核壳结构,降低冲击感度,提高热稳定性。此外,还可制备聚四氟乙烯/铝(PTFE/Al)等复合炸药,提升反应特性。总之,超声技术在含能材料制备中前景广阔,为新型材料开发提供新路径。未来需进一步探索超声安全机制,开发专用工艺技术与设备,推动其在含能材料制备中的安全工业化应用。
Ultrasonic technology significantly advantages the preparation of composite energetic materials by reducing crystal metastable zone,shortening nucleus formation time,and preventing fragment crystal aggregation,thereby assisting in the creation of high-performance organic nanocrystals.The ultrasonic-assisted emulsification technique facilitates the production of microspherical co-crystals,enhancing mechanical sensitivity.Additionally,ultrasonic technology enables the fabrication of core-shell structures such as HMX@TATB and AP@TATB,reducing impact sensitivity and improving thermal stability.Furthermore,it can be used to prepare composite explosives such as PTFE/Al,enhancing reactivity.In conclusion,ultrasonic technology holds immense potential in energetic material synthesis,offering new avenues for novel material development.Future efforts should focus on elucidating the ultrasonic safety mechanism,developing specialized process technologies and equipment,and promoting its safe industrial application in energetic material manufacturing.
