Hollow energetic microspheres have attracted great attention in the field of materials due to their wide application potential. However, scalable, simple, and low-cost production methods not been achieved yet. In this study, using nitrocellulose (NC) as a binder, hollow porous CL-20 were prepared by assist microjet droplet technology. The effects solution concentration, receiving liquid temperature, solvent type on morphology, particle size, shell thickness, pore size systematically investigated. Furthermore, influences thickness dispersibility, crystal structure, thermal decomposition, mechanical sensitivity, combustion behavior further studied. results showed that precise control over could be adjusting experimental parameters. Compared raw CL-20, exhibited excellent dispersibility improved safety performance. Ignition experiments demonstrated structures significantly enhanced flame energy release efficiency. This preparation method is simple efficient, providing new approach for fabrication multi-structured microspheres.

Energetic materials, characterized by their capacity to store and release substantial energy, hold pivotal significance in some fields, particularly defense applications. Microfluidics, with its ability manipulate fluids facilitate droplet formation at the microscale, enables precise control of chemical reactions. Recent scholarly endeavors have increasingly harnessed microfluidic reactors realm energetic yielding morphologically controllable particles enhanced uniformity explosive efficacy. However, crucial insights into microfluidic-based methodologies are dispersed across various publications, necessitating a systematic compilation. Accordingly, this review addresses gap concentrating on synthesis materials through microfluidics. Specifically, methods based micro-mixing droplets previous papers summarized strategies critical parameters within reactions discussed detail. Then, comparison terms advantages disadvantages is attempted. As demonstrated last section regarding perspectives, challenges such as clogging, dead zones, suboptimal production yields non-ignoble promising fields they might be addressed integrating sound, optics, or electrical energy meet heightened requirements. This comprehensive overview aims consolidate analyze diverse array approaches material synthesis, offering valuable for future research directions.

As a typical high-energy-density material, the sensitivity of CL-20 severely limits its application in explosives and propellants. Adjusting structure at microscopic level can effectively solve such problems. In this study, microfluidic recrystallization technique was used to prepare ε-CL-20 with three different particle sizes, narrow size distributions (D50 = 2.77 μm, 17.22 μm 50.35 μm). The prepared samples had fewer surface defects compared raw material. decreased, density increased impact significantly reduced. activation energy using technology increases size. Laser ignition experiments revealed that smaller particles highest release efficiency, while larger exhibited higher more stable release. combustion performance safety be improved by improving crystal distribution morphology. Controllable preparation multiple sizes achieved technology, which provides reference for other energetic materials.
