纳米多孔硅基复合含能材料的研究进展

Progress of Research on Nanoporous Silicon-based Composite Energetic Materials

综述了纳米多孔硅和纳米多孔硅基复合含能材料的国内外研究现状,通过分析认为该类复合含能材料具有反应活性高、能量可控、性能可调以及燃烧产物污染小等优点,具有很好的应用前景,但从目前的研究现状来看,还存在感度高、安全性能差、易氧化等缺点,且其爆炸反应机理也不明确,还需进一步进行制备工艺和爆炸反应机理方面的研究。

As a new kind of nanometer energetic materials, the research progresses of nanoporous silicon and nanop-orous silicon based composite energetic materials were reviewed. From the comparative analysis, it was found that this kind of composite energetic materials has advantages of high reaction activity, controllable energy management, tunable properties and less pollution of combustion products ete, and has good application foreground. However, it still has some disadvantages according to the present research situation, such as high sensitivity, poor safety and easily oxidized etc. The mechanism of explosion reaction is not studied in details, therefore it needs further research on the aspects of preparation technology and explosion reaction mechanism.
