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

Temperature-dependent decomposition of the CL-20/MTNP cocrystal after phase separation

“…Actually, the CL-20/TNT presented two exothermic peaks when it decomposed at low temperature, 44 while only one exothermic peak was observed during high temperature decomposition. 45 Of course, the surface defects, intermolecular interactions and experimental conditions also have a significant effect on the decomposition mechanism. The more surface defects there were, the easier the initial decomposition was.…”

Preparation of μ-HMX/C-Based Composite Energy Composite Microspheres by Microdroplet Technology

“…23,24 Domestic and foreign teams have successfully applied microdroplet technology in the field of energy-containing materials. In 2018, Wu et al 25 realized the integrated preparation of CL-20/TNT eutectic assembly and spherical coatings. in 2022, Li et al 26 et al 27 prepared HNS/CL-20 composite energy-containing microspheres using poly glycidyl azide polymer (GAP) as a binder.…”

“…Microdroplet technology is to realize microscale uniform droplets by controlling the fluid and to solve the difficulties in the traditional production process by controlling the reaction process in the droplets. − Microdroplet technology has a wide range of applications in the fields of biomedicine, chemical synthesis, and material modification and provides a new direction for the preparation of composite explosives. − Different droplet formation methods include coaxial droplet chips, , T-shaped droplet chips, , and cross-focused focused droplet chips. , Domestic and foreign teams have successfully applied microdroplet technology in the field of energy-containing materials. In 2018, Wu et al realized the integrated preparation of CL-20/TNT eutectic assembly and spherical coatings. in 2022, Li et al developed a continuous preparation of TATB/HMX composite particles.…”

Construction of hollow heterogeneous microspheres containing energy storage fibers by electric spray to promote combustion of nano aluminum

“…How can we assemble AP, nAl and fluoropolymer together? Common preparation methods in the literature, such as sol-gel [25][26][27][28][29][30][31], microfluidic [32][33][34][35][36][37][38][39], solvent-antisolvent coating [40][41][42][43], and spray drying [44][45][46][47][48], had their own shortcomings. For example, sol-gel was easy to introduce impurities, and later drying needs freeze drying or supercritical drying.…”
