“…As illustrated in Fig. S7,† for pristine RDX, 40 the presence of two absorption peaks at 3070 and 3000 cm −1 are attributed to the asymmetric stretching vibration of C–H; the absorption peak at 1600 cm −1 is the antisymmetric stretching vibration corresponding to the presence of an –NO 2 group. The occurrence of absorption peaks at 1270 and 1220 cm −1 refers to the stretching vibration of the N–N bond, whereas the absorption peaks at 1040 and 926 cm −1 are related to the stretching vibration of C–N, and the absorption peak between 781 and 586 cm −1 corresponds to the deformation vibration of –NO 2 .…”

“…From another prospective, the hydrothermal treatment would be a pathway for handling energetic materials as the water medium was extremely safe for the explosives even with some solvent inside. 37,39,40 Previously mentioned literature and strategies would provide reliable references for the combination of high-sensitive explosive RDX and low-sensitive explosive TATB.…”

Composite microcrystals of the cyclic nitramines 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (ε-CL-20), 1,3,5-trinitro-1,3,5-triazinane(RDX), 1,3,5,7-tetranitro-1,3,5,7-tetrazocane (β-HMX), and cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) with polyaniline (PANi) have been prepared and thoroughly characterized in terms of morphology and phase purity. PANi outperformed other conducting polymers in terms of selectivity towards NAs due to its better interaction with NAs, low production cost, and ease of preparation. The bonding of nitramines with the polymeric PANi chain has been examined by means of Fourier transform infrared (FTIR), Raman spectroscopy methods, and fluorescence quenching; the Raman spectrum has shown the laser sensitivity of these microcrystals. Powder X-ray diffraction results have shown changes in polymorph modifications in CL20 (from ɛ to β) and HMX (from β to α) during the preparation of the composites, which have also been confirmed by spectral and differential thermal analysis techniques. The structural orientations found in these composites significantly stabilize nitramines against impact; their detonation properties have slightly deteriorated, but the PANi electrical conductivity has strongly increased their electric-spark sensitivity. The above properties of the prepared composites determine their potential use mainly as parts of the electric or laser impulse initiators, having “a green character”, for various charges.
