“…As one class of them, nano-explosives have attracted much attention due to their potential application in micro thrusters [6] and micro-electromechanical systems [7]. Recently, benefiting from the development of nanotechnology, a variety of nano-explosives such as 1,3,5-trinitro-1,3,5-triazinane (RDX) [8,9], HMX [10,11], 1,1-diamino-2,2-dinitroethene (FOX-7) [12,13], 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazawurt-zitane (CL-20) [14,15] and TATB [16,17] have been successfully prepared by various approaches. With respect to LLM-105, Zhang et al [18] utilized a spray-crystalline method to prepare submicron size LLM-105.…”

In this study, nanoparticles stacked 2,6‐diamino‐3,5‐dinitropyrazine‐1‐oxide (LLM‐105) sub‐microspheres were successfully fabricated by electrospray deposition. These monodisperse sub‐microspheres with a diameter from 200–500 nm are composed of 50 nm nanoparticles, and after preserved six months these spheres retain the same structure and morphology. The effect of process parameter including flow rate and nozzle size on the size and morphology of sub‐microsphere is investigated. The results show that, for a given solution concentration the nozzle size has little effect while the flow rate shows a significant effect. The X‐ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT‐IR) results exhibit that the as‐prepared sub‐microspheres have the same crystal and chemical structure as the raw materials. The thermal behavior performed by simultaneous thermal analysis (TG‐DSC) verifies that in comparison to the raw materials sub‐microspheres have a lower onset degradation temperature.

“…Of course, nanosized FOX-7 was also included. In 2010, FOX-7 quasi-three-dimensional (3D) grids of onedimensional nanostructures were synthesized via a sprayfreeze-drying technique by Huang et al [18]. The results showed that the reduction in the average particle size of the FOX-7 grid structure leads to lower decomposition temperature and higher decomposition rate.…”

Nanoparticle-stacked 1,1-diamino-2,2-dinitroethylene (FOX-7) microspheres were successfully prepared by spray-drying, and rod-shaped FOX-7 was obtained by the solvent/nonsolvent method for comparison. The microstructure features of samples were characterized using scanning electron microscopy (SEM) and powder X-ray diffraction (XRD), and the thermal properties were also investigated by differential scanning calorimetry (DSC). From the SEM analysis, the particle size of the rod-shaped FOX-7 is about 10 μm, whereas FOX-7 microspheres having a particle size ranging from 1 to 5 μm are formed by stacking nanoparticles with size of 100-250 nm. The crystal form of the samples prepared by the two methods did not change. The thermal performance test results showed that the rd-shaped FOX-7 had no significant change compared with the raw FOX-7, while the nanoparticle-stacked FOX-7 microspheres had higher thermal stability.

“…[1,2] Many related researches on FOX-7 are reported every year, including theoretical and applied researches. [3][4][5][6][7][8][9][10][11][12][13] A lot of new energetic derivatives of FOX-7 have been reported continually in the past 20 years. [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Molecular structure of FOX-7 is very simple, only containing two amino groups and two nitro groups connected with an ethylene group, but its reactivity is abundant, which have been systematically summarized in a review by our group.…”

Two energetic compounds, 1‐amino‐1‐picrylamino‐2,2‐dinitroethylene (APDE) and its potassium salt [K(APDE)] were synthesized through an aromatic nucleophilic substitution reaction between FOX‐7 and picryl chloride. APDE and K(APDE) were characterized by elemental analysis, IR, NMR spectroscopy, and X‐ray diffraction. APDE has a 3D wavy layered stacking structure similar to FOX‐7. K(APDE) (peak temperature (Tip)=185.6 °C and impact sensitivity (IS)=19.6 J) presents better stability than APDE (tap=133.3 °C and IS=15.7 J). The reasons why the stability of APDE is lower than that of FOX‐7 and picryl chloride are analyzed. The detonation velocity (D) and detonation pressure (P) of APDE (8.36 km s−1 and 31.3 Gpa) are close to those of FOX‐7 and RDX. The thermal decomposition of K(APDE) is very violent, and its detonation performance (D=9.14 km s−1 and P=38.6 Gpa) is comparable to that of HMX, indicating that K(APDE) has good potential to be a high explosive.
