| Summary: | Cocrystal belongs to supramolecular chemistry and it is generally composed of different components including molecules, ions with certain molecular ratio and typical structure. For energetic cocrystals, cocrystallization technology can apply the intermolecular interactions between different energetic material molecules to form special crystal to solve the contradictory between energy density and safety. Besides, cocrystallization method can also overcome some shortcomings of raw component and improve the comprehensive properties of energetic materials. Up to now, there are numerous 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) based cocrystals have been successfully synthesized and characterized. Among them the reported CL-20 based cocrystals, the 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane/ octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (CL-20/HMX) cocrystal maintains high energetic performance of CL-20, and the mechanical sensitivity is lower than pure CL-20, realizing the goal of desensitization and making it a promising and novel high energy energetic cocrystal. Hence, the CL-20/HMX energetic cocrystal has attracted wide attention worldwide. Therefore, in this work, the research progress of CL-20/HMX cocrystal explosive was summarized, including preparation method, characterization method, performance test, theoretical investigation. The application prospect and outlook of CL-20/HMX cocrystal explosive were pointed out, including exploring new methods to obtain batch production of CL-20/HMX cocrystal and fabricate CL-20/HMX based PBXs or propellants to make this energetic cocrystal exhibit more desirable comprehensive physicochemical performances and to be applied in practice. |
