含能共晶，特别是CL-20基共晶，由于其感度低、爆轰性能好而受到广泛关注。本研究采用电喷雾沉积法成功制备了一系列纳米级CL-20基含能共晶。对于CL-20/TNT纳米共晶，研究了不同溶剂对共晶形貌和晶体结构的影响。结果表明，所有的CL-20/TNT电喷雾样品均为部分共晶形成，且以酮为溶剂制备的共晶颗粒尺寸小于以乙基为溶剂制备的共晶颗粒尺寸。相比之下，电喷雾CL-20/DNB纳米共晶通过DSC和PXRD证明完全形成了共晶结构。此外，太赫兹（THz）结果证实了分子间氢键的形成。此外，我们还首次采用电喷雾法制备了CL-20/TNB共晶。PXRD和DSC结果证实了这种结构的形成。
Energetic cocrystals, especially CL-20-based cocrystals, have attracted a wide range of attention due to their low sensitivity and impressive detonation performance. In this study, a series of nanosized CL-20-based energetic cocrystals were successfully fabricated by electrospray deposition. For CL-20/TNT nanococrystals, the influence of different solvents on the morphology and crystal structure of as-prepared cocrystals were investigated. The results showed that all the electrosprayed CL-20/TNT samples were partial formation of cocrystals and particles obtained from ketone had smaller size than those obtained from ethyl solvents. In contrast, electrosprayed CL-20/DNB nanococrystals had completely formed the cocrystal structure proved by DSC and PXRD. Moreover, the terahertz (THz) result confirmed the formation of intermolecular hydrogen bonds. Additionally, we have fabricated the CL-20/TNB cocrystals for the first time by using electrospray method. The PXRD and DSC results confirmed the formation of this...
