Abstract: On the basis of our previous Molecular Dynamics (MD) Simulation (Wei, C. X.; Huang, H.; Duan, X. H.; Pei C. H. Propell. Explos. Pyrot. 2009, 67, 2822-2826), a cocrystal explosive (CCE) consisting of octahydro-1,3,5,7- tetranitro-1,3,5,7-tetrazocine (HMX) and 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) has been prepared with a solvent/nonsolvent (S/NS) process. Scanning electron microscopy (SEM) demonstrated that crystal morphology of the CCE was significantly improved in contrast to the crystal of HMX and TATB. Differential scanning calorimetry (DSC) showed that the CCE exhibited the enhancement of thermal stability and became less sensitive to impact, compared with the HMX. Raman spectroscopy, terahertz time-domain spectroscopy (THz-TDS), and X-ray photoelectron spectroscopy (XPS) provided characterization at the molecular level. The results indicated that the main mechanism of cocrystal originates from the N-O · · · H hydrogen bonding between-NO 2 (HMX) and-NH2 (TATB). © 2011 American Chemical Society.
