摘要/Abstract

摘要： 原位合成是解决微小火工品装药问题的关键技术。为探究金属有机骨架材料孔径对原位合成叠氮化铜的影响，采用普通溶液法制备得到3种不同孔径的含铜金属有机骨架化合物，在高温碳化后进行叠氮化反应，最终得到叠氮化铜-碳复合起爆药。利用氮气吸附脱、扫描电镜、粉末X射线衍射以及差示扫描量热法等表征手段，对各阶段产物进行测试分析。结果表明：孔径大小会影响到骨架中铜的叠氮化程度，孔径越大，叠氮化反应越充分。

Abstract: In-situ synthesis is a key technology to solve the problem of tiny explosive charges. In order to explore the influence of pore size of metal-organic frameworks on the in-situ synthesis of copper azide，three kinds of copper-containing metal-organic frameworks with different pore sizes were prepared by ordinary solution method. The azide reaction is carried out after high-temperature carbonization，and finally a copper azide-carbon composite primary explosive is obtained. The products at each stage are characterized using nitrogen adsorption and desorption，SEM，PXRD， DSC and other characterization methods. The results indicate that the pore size affect the azide degree of copper in the framework，and the larger the pore size is，the more sufficient the azide reaction will be.
