摘要
通过对比金属燃料的氟化/氧化生成物的生成焓及相变温度等物理化学性质的差异,归纳总结了金属基含能体系的氟化释能反应特征及其潜在应用优势;从典型含氟氧化剂种类及其特性,以及含氟氧化剂在烟火药、推进剂、炸药及铝热剂中的应用等方面,对基于含氟氧化剂的复合含能体系的研究进展进行了梳理;对含氟氧化剂在复合含能体系中的应用研究发展方向进行了展望.指出应系统开展基于不同氟源的复合含能体系的计算化学研究,从原子/分子层面加深对基于氟化反应的热力学和动力学机制及其构效关系的理解;此外,还应加深对燃烧反应氟转移机制及预点火条件下界面间氟渗入机理的研究;在此基础上,从纳米建筑学和反应路径设计的角度,开发适用于不同场景的含能材料的新型含氟氧化剂.附参考文献137篇.
Abstract
By comparing the differences in the physical and chemical properties,such as the enthalpy of formation and phase transition temperatures of the fluorinated/oxidized products of metal fuels,the characteristics and potential application advanta-ges of fluorination energy release reactions in energetic systems were summarized.The research progress of composite energet-ic systems based on fluorinated oxidizers,including typical types and characteristics of fluorinated oxidants,as well as their ap-plications in pyrotechnics,propellants,mixed explosives,and aluminum thermites has been reviewed.The research and devel-opment direction of the application of fluorine-containing oxidizers in composite energetic systems was prospected.It is pointed out that the systematic computational chemistry research on composite energetic systems based on different fluorine sources should be conducted to understand the thermodynamic and kinetic mechanisms of fluorination reactions and their structure-activ-ity relationships at the atomic/molecular level.Furthermore,research should also be intensified on the fluorine transfer mecha-nism in combustion reactions and the interfacial fluorine infiltration mechanism under pre-ignition conditions.Based on this,new typical fluorine-containing oxidizers suitable for different scenarios should be developed from the view point of nano architec-tonics and reaction pathway design.Attached with 137 references.
