能够按需储存并快速释放大量化学能的含能材料在军事和民用领域都发挥着至关重要的作用。现代含能材料应具有高密度、高形成热并具有分子稳定性，以便安全地制造、储存和处理。最近，共晶技术为含能材料提供了一个有前途的平台，以实现高爆轰性能和低灵敏度之间的理想平衡。本文重点介绍了高能共晶体的最新进展，并详细介绍了分子间相互作用、物理参数和爆炸特性。讨论的主要内容涉及不同类型的含能共晶，包括由含能分子和溶剂组成的共晶、2,4,6,8,10,12-六硝基六氮杂异伍兹烷（CL-20）基共晶和唑基共晶等。此外，还介绍了共振声混合（RAM）技术、珠磨和喷雾闪蒸技术作为大规模生产纳米含能共晶的手段。
Energetic materials that can store and rapidly release large amounts of chemical energy on demand play a vital role in both military and civilian fields. Modern energetic materials should have high density, high heat of formation and possess molecular stability that allow them to be manufactured, stored and handled safely. Recently, cocrystallization technology offers a promising platform for energetic materials to achieve a desired balance between high detonation performance and low sensitivity. This paper highlights recent developments of energetic cocrystals and details intermolecular interactions, physical parameters and detonation properties. The major part of the discussion relates to the different types of energetic cocrystals including cocrystals composed of energetic molecules and solvents, 2,4,6,8,10,12-hexanitrohexaazaisowurtzitane (CL-20)-based cocrystals and azole-based cocrystals, et al. In addition, resonant acoustic mixing (RAM) technique, bead milling and spray flash evaporation technique are also introduced as means for large-scale production of nanosized energetic cocrystals.
