The Effect of Particle Size of Copper Oxide (CuO) on the Heat-Induced Catalysis Decomposition of Molecular Perovskite-Based Energetic Material DAP-4

In this study, the effect of copper oxide (CuO) with different sizes on heat-induced catalysis decomposition typical molecular perovskite-based energetic material DAP-4 was studied. Pure CuO and are characterized by X-ray diffraction (XRD) scanning electron microscopy (SEM). Heat-induced performances adding were investigated differential calorimeter (DSC). Results demonstrated that a lower-addition at nanoscale added (1 wt%), had decreased least 36°C heating rate 10°C/min, compared pure DAP-4. With particle size 50 nm, E a in DAP-4/CuO-50 reduced from 159.8 kJ/mol to 120.2 kJ/mol, which is lower than DAP-4/CuO-150. The mechanism using as nanoadditive proposed.
