Abstract

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