Abstract EN
Spray drying method was used to prepare cocrystals of hexanitrohexaazaisowurtzitane (CL-20) and cyclotetramethylene tetranitramine (HMX).
Raw materials and cocrystals were characterized using scanning electron microscopy, X-ray diffraction, differential scanning calorimetry, Raman spectroscopy, and Fourier transform infrared spectroscopy.
Impact and friction sensitivity of cocrystals were tested and analyzed.
Results show that, after preparation by spray drying method, microparticles were spherical in shape and 0.5–5 µm in size.
Particles formed aggregates of numerous tiny plate-like cocrystals, whereas CL-20/HMX cocrystals had thicknesses of below 100 nm.
Cocrystals were formed by C–H⋯O bonding between –NO2 (CL-20) and –CH2– (HMX).
Nanococrystal explosives exhibited drop height of 47.3 cm, and friction demonstrated explosion probability of 64%.
Compared with raw HMX, cocrystals displayed significantly reduced mechanical sensitivity.
