Recent Progress on Synthesis, Characterization, and Performance of Energetic Cocrystals: A Review

Molecules, Journal Year: 2022, Volume and Issue: 27(15), P. 4775 - 4775

Published: July 26, 2022

In the niche area of energetic materials, a balance between energy and safety is extremely important. To address this “energy–safety contradiction”, cocrystals have been introduced. The investigation synthesis methods, characteristics, efficacy utmost importance for optimizing their design development. This review covers (i) various methods cocrystals; (ii) discusses characteristics such as structural properties, detonation performance, sensitivity analysis, thermal morphology mapping, along with other properties oxygen balance, solubility, fluorescence; (iii) performance respect to contents (detonation velocity pressure) sensitivity. followed by concluding remarks together future perspectives.

Novel approach for preparation of the energy-safety balanced cocrystals of attractive nitramines via coagglomeration

FirePhysChem, Journal Year: 2024, Volume and Issue: 4(4), P. 283 - 294

Published: March 6, 2024

Co-agglomeration unique crystal engineering approach; in which the co-precipitated micro-particles of nitramines with other energetic materials co-agglomerated by slurry method; to modify properties attractive like CL20, HMX, BCHMX, and RDX etc. The interesting structural modifications newly prepared crystals (CACs) one are discussed here. There notable variations morphologies packing crystals, including key relatively high density, melting point, impact sensitivity, detonation properties. These CACs overwhelming majority showing co-crystals. Apart from these aspects, co-agglomeration provides a huge opportunity tune performance existing is easy scale-up for industrial level. preliminary results also suggest that chemical factors involved preparation have tremendous improvements than conventional crystallization. With technological optimization this method can be employable scale production.

Study on Mechanical Improvement of CL‐20 Energetic Co‐Crystals Based PBX by Surface Modification

Propellants Explosives Pyrotechnics, Journal Year: 2023, Volume and Issue: 48(4)

Published: Feb. 10, 2023

Abstract Low melting point compound MTNP was usually adopt to form co‐crystal explosive with CL‐20 reduce sensitivity, and the may have potential of green engineering application. Improving mechanical properties co‐crystals is one effective ways broaden its practical In this work, CL‐20/MTNP energetic selected be coated by polydopamine (PDA) neutral bonding agent (NBA), enhanced developed interfacial strength between crystal binder. The TG‐DSC curve showed that thermal decomposition explosives divided into two steps, delayed 210 °C compared MTNP. After surface modification, storage modulus PBX increased more than 20 % at temperature range (25–120) °C, creep strain also effectively reduced. Brazilian compressive PDA coating samples 69.89 210.53 respectively, as well improved elongation, leading fracture toughness. Here, highlighted modification on can used a reference insight improve new explosives.
