摘　　要：六硝基六氮杂异伍兹烷(HNIW,CL-20)是一种高能量密度新型含能材料,在单质炸药、混合炸药以及推进剂等方面有着广泛的应用前景。但是CL-20感度较高的特点限制了其进一步推广应用,对CL-20晶体进行晶体修饰处理可以有效地降低其感度。概述国内外CL-20晶体修饰降低感度技术研究进展,总结了共结晶和核壳结构包覆两种主要的晶体修饰降感方法,并对不同方法降感机理进行分析。对共结晶和核壳结构包覆这两种降感方法的研究现状进行梳理并对降感效果进行了总结和对比,最后分析该领域的研究趋势。Hexanitro-hexaazaisowurtziane( HNIW,CL-20) is a new energetic material with high energy density.It has broad application in explosive,mixed explosive and propellant.However,high sensitivity of CL-20 limits its further application.Crystal modification of CL-20 crystal can effectively reduce its sensitivity.The research progress of CL-20 crystal modification and sensitization reduction technology domestic and foreign is summarized.Main crystal modification methods are discussed,which are modification of cocrystal method and construction core-shell structure method.The mechanism of sensitization reduction by different methods is analyzed.Two different methods of decreasing sensitivity were introduced and effects of these different crystal methods in sensitivity decrease are compared.Finally,tendency of the research field is pointed out.
