摘　　要：系统综述了含氟材料助燃硼粉的研究进展,并分析了助燃机制。研究表明,不论无机含氟材料、有机含氟材料还是自组装含氟材料,对硼粉燃烧都有一定的助燃效果。但是,不同含氟材料对硼粉的助燃效果有很大差异,新兴的自组装含氟材料结构规整,可能极具应用价值,值得深入研究。分析表明,含氟材料的助燃机制为氟自由基或含氟基团的自由基的催化作用,该发现对材料的应用场景具有重要参考意义。综合大量文献研究,作者首次提出,氢含量低、易于热解且热解时易产生氟原子及含氟烷烃、含氟烯烃的自由基的材料,对硼粉会具有更好的助燃效果。研究结果预计对火炸药行业从业者会有重要的参考价值。The research progress of combustion-supporting effect of fluorine-containing materials on boron powders is systematically reviewed,and the combustion-supporting mechanism is analyzed in the paper.The research results showed that no matter inorganic fluorine-containing materials,organic fluorine-containing materials or self-assembled fluorine-containing materials,they had certain combustion-supporting effects on the combustion of boron powder.However,there are significant differences in the combustion supporting effects of different fluorine-based materials on boron powder.The emerging self-assembled fluorine-based materials have a regular structure and may have great application value,which is worthy of in-depth research.Analysis shows that the combustion supporting mechanism of fluorine-based materials is the catalytic effect of fluorine free radicals or free radicals containing fluorine groups,which has important reference significance for the application scenarios of materials.Based on a large number of literature data,the paper proposes for the first time that materials with low hydrogen content,easy pyrolysis and easy to produce fluorine atoms and free radicals containing fluoroalkanes and fluoroalkenes during pyrolysis will have better combustion-supporting effect on boron powder.The research results of the paper are expected to have important reference value for practitioners in the explosives and propellants industry.
