Highly energetic materials have received significant attention, particularly 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20). However, the application of this material was limited due to its high sensitivity. It is well known that the shape, size, and structure of energetic materials (EMs) significantly influence their sensitivity. At present, there are several ways to reduce the sensitivity of CL-20, such as spheroidization, ultrafine processing, and composite technology. However, only one or two of the abovementioned methods have been reported in the literature, and the obtained sensitivity effect was unsatisfactory. Thus, we tried to further reduce the sensitivity of CL-20 by combining the above three methods. The as-prepared composite was precipitated from the interface between two solutions of water and ethyl acetate, and the composite was insensitive compared with other reported CL-20-based EMs. The H value for the composite ranged up to 63 cm. This approach opens new prospects for greatly reducing the sensitivity of high Ems.
高能材料受到了广泛关注，尤其是2,4,6,8,10,12-六硝基-2,4,6,8,10,12-六氮杂异伍兹烷（CL-20）。然而，这种材料因其高灵敏度而应用受限。众所周知，高能材料的形状、尺寸和结构会显著影响其灵敏度。目前，有几种方法可以降低CL-20的灵敏度，如球化、超细化处理和复合技术。然而，文献中仅报道了上述方法中的一两种，且获得的灵敏度效果并不理想。因此，我们尝试通过结合上述三种方法来进一步降低CL-20的灵敏度。所制备的复合材料是从水和乙酸乙酯两种溶液的界面沉淀出来的，与其他报道的基于CL-20的高能材料相比，该复合材料不敏感。该复合材料的H值高达63厘米。这种方法为大幅降低高能材料的灵敏度开辟了新前景。
