Nitramine-Based Energetic Cocrystals with Improved Stability and Controlled Reactivity

Crystal Growth & Design, Journal Year: 2020, Volume and Issue: 20(12), P. 8124 - 8147

Published: Nov. 11, 2020

The inherent contradiction between the energy density and safety of energetic materials (EMs) is very challenging. To solve this problem, cocrystallization technology has been usually used in field EMs to better balance safety. preparation techniques cocrystals mainly include solvent evaporation, solvent/nonsolvent, grinding methods. prepared by these methods have structures completely different from starting crystals. comprehensive performance (ECCs), such as density, solubility, sensitivity, thermal stability, significantly improved. This review summaries ECCs their fundamental formation mechanisms, where HMX-based CL-20-based are selected typical examples. Their structures, thermodynamic characteristics, detonation parameters summarized compared detail. Finally, future research directions challenges proposed based on literature survey.

One-step rapid preparation of CL-20/TNT co-crystal assembly and spheroidized coating based on droplet microfluidic technology

Defence Technology, Journal Year: 2022, Volume and Issue: 27, P. 251 - 262

Published: Oct. 7, 2022

Energetic materials pose challenges in preparation and handling due to their contradictory properties of high-energy low-sensitivity. The emergence co-crystal explosives is a new opportunity change this situation. If the explosive coated into spherical particles with uniform particle size distribution, contradiction can be further reduced. Therefore, binder-coated hexanitrohexaazaisowurtzitane/2,4,6-trinitrotoluene (CL-20/TNT) microspheres were prepared by droplet microfluidic technology work. coating effects different binder formulations nitrocellulose (NC) NC/fluorine rubber (F2604) on spheres studied. scanning electron microscopy (SEM) results showed that use above binders provide regular morphology, distribution good dispersion. X-ray diffraction (XRD), fourier-transform infrared (FT-IR), differential calorimetry (DSC) thermo-gravimetric (TG) methods employed compare microspheres, raw material pure co-crystal. formation CL-20/TNT was confirmed, exhibited better thermal stability than In addition, mechanical sensitivity combustion performance more insensitive CL-20 co-crystal, displayed excellent self-sustained theoretical detonation performance. This study provides method for fast, simple one-step coating, level.
