金属有机骨架材料孔径对原位合成叠氮化铜- 碳复合起爆药的影响规律

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.
