    摘要:

    共晶是指不同种类的中性组分在分子间非共价键的作用下形成的具有固定比例与特殊结构的晶体,属于超分子领域范畴。共晶技术是一种新型的含能材料改性方法手段,具有广阔的发展前景与应用价值。共晶可以降低含能材料的感度,提高安全性,改善力学性能、热性能与能量密度。综述了含能共晶制备及应用研究进展,其中包括共晶炸药国内外研究现状、制备方法、表征方法、形成机理。介绍了含能共晶面临的问题:部分共晶炸药性能有待进一步改善;共晶炸药制备条件苛刻,产率低;共晶炸药的测试表征手段较为单一。指出了今后研究的重点方向为:加强多组分含能共晶的研究;改善共晶炸药制备工艺,提高产量;研究共晶的结晶动力学行为,寻求共晶的最佳结晶条件以及寻找良好的表征共晶结构的方法手段。

    Abstract:

    Cocrystal is composed of different neutral components through intermolecular non-bond interactions at molecular level and it has fixed ratio and particular structure. Cocrystallization technology is a novel method for ameliorating properties of energetic materials and it has wide development prospect and application value. It can decrease the sensitivity, improve the mechanical properties, thermal performance, and energy density of energetic materials. The research progress of preparation and application of energetic cocrystals was summarized, including the current research status, preparation method, characterization methods, and formation mechanism. The existing problems of energetic cocrystals were introduced: first, the properties of some cocrystal explosives need to be further improved; second, the preparation of cocrystal requires harsh conditions with low product yield; third, the characterization and test methods lack variety. The further development direction of cocrystal explosives were pointed out: strengthen the research of multiple components energetic cocrystals, improve the technologies to increase the yield, investigate the crystallization dynamics behavior to seek for the best cocrystallization conditions, and look for effective means to characterize the cocrystal structure.
