Abstract

The invention discloses a method for preparing an ordered porous energetic crystal material. The method comprises the following steps of: dissolving a certain amount of energetic materials in a good solvent at room temperature; adding a certain amount of crystal morphology control agents into the solution in the previous step, stirring, dissolving, and slowly adding the solution in the previous step into a poor solvent of the energetic materials and the crystal morphology control agents under the magnetic stirring conditions; continuously stirring the solution in the previous step for a certain time, filtering, and obtaining a composite material of the energetic materials and the crystal morphology control agents; adding the obtained composite material into the solvent, wherein the solvent is a poor solvent of the energetic materials and a good solvent of the crystal morphology control agents; repeatedly washing and removing the crystal morphology control agents; and drying to obtain pure ordered porous energetic crystal material. The preparation method is simple in process flow and mild in reaction conditions and suitable for various energetic materials, the reaction conditions are easy to control, and the prepared ordered porous energetic crystal material has the purity of over 99.5 percent.

Description

technical field [0001] The invention belongs to the field of energetic materials, and in particular relates to a preparation method of an ordered porous energetic crystal material. Background technique [0002] Ordered porous material is a new type of nanostructured material that emerged rapidly in the 1990s. It has been highly valued by the international physics, chemistry and materials science circles since its birth, and has rapidly developed into one of the interdisciplinary research hotspots. Ordered porous materials have the characteristics of uniform pore size, orderly arrangement, and continuous adjustment of pore diameter within a certain range. etc. have broad application prospects. Therefore, the application of porous materials in the research of energetic materials will definitely expand and deepen the research of energetic materials. [0003] Energetic materials, mainly including explosives, propellants, and pyrotechnic agents, are multifunctional materials th...
