- Abstract
Nano-sized energetic co-crystal consisting of the most powerful used military explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20) and a typical insensitive explosive used in propellants nitroguanidine (NQ) was prepared by vacuum freeze drying method. Material studio 6.1 was used to simulate the hydrogen bonds between CL-20 and NQ molecules. Scanning electron microscopy (SEM) was used to reveal the morphology and size of the product. Fourier Transform infrared spectroscopy (FT-IR) and X-ray diffraction spectrum (XRD) proved the formation of the co-crystal at the molecular level. Differential scanning calorimetry (DSC) was employed to characterize the thermal behavior of the co-crystal. The result of mechanical sensitivity test indicated the sensitivity was effectively reduced compared to neat CL-20.
