Enhanced thermal decomposition performance of sodium perchlorate by molecular assembly strategy

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

“…CuO at the nanoscale still showed a good catalysis performance in the propellant due to the strong heat and mass transfer capabilities of nano-CuO nanoparticles or clusters. For pure DAP-4, the high thermal stability is from the cage-like framework of perovskite structure [17,[31][32][33]. Therefore, more energy needs to be provided to destroy the cage-like framework structure at a higher heat-induced decomposition temperature.…”

“…At the molecular level, DAP-4 integrated with fuel dabco and oxidizer ammonium perchlorate to show high-energy performances. But huge heat-induced decomposition threshold of molecular perovskite-based energetic materials is always not beneficial for the ignition and combustion [17,18]. But high heatinduced decomposition temperature of molecular perovskite-based energetic materials usually restricted their novel and possible applications.…”

Thermal kinetics, thermodynamics, decomposition mechanism, and thermal safety performance of typical ammonium perchlorate-based molecular perovskite energetic materials

“…The initial thermal decomposition D r a f t temperature is 360 °C, and the thermal decomposition peak temperature is higher than 400 °C. Compared from the existing high heat resistant explosive hexanitrostilbene (HNS), DAP-4 showed good stability and compatibility [16][17][18][19][20][21][22][23][24][25][26] .…”

First-principles study on the mechanical and electronic properties of energetic molecular perovskites AM(ClO4)3 (A = C6H14N22+, C4H12N22+, C6H14N2O2+; M = Na+, K+)

“…[14][15][16] The lack of knowledge about fundamental mechanical properties and electronic properties of energetic molecular perovskites is not conducive to the further development of these promising energetic materials. However, the studies on energetic molecular perovskites mainly focus on the synthesis of new structures and thermal decomposition properties, [17][18][19][20][21][22][23] have been conducted on the mechanical and electronic properties on energetic molecular perovskites. 24 Therefore, it is a great interest to research the mechanical and electronic properties of molecular perovskite high-energetic materials.…”
