Abstract Ammonium perchlorate (AP) plays an important role in solid propellants because of its high specific impulse, energy density and low cost. However, the excellent performance cannot conceal many shortcomings AP, problems non‐concentrated exothermic, sensitivity hygroscopicity still seriously impede application propellants. In this study, solvent evaporation method is used to directionally modify order cupric oxide (CuO) fluororubber (F 2603 ) shell layers so as obtain AP‐based composites with different core‐shell structures. The interlayer binding energies structures are explored by theoretical calculations, it demonstrated that have stability. addition, CuO valence‐band holes not only reduces peak temperature decomposition AP (440.4 354.5 °C), but also enhances combustion properties undergoing thermite reaction Al. Furthermore, hydrophobicity barrier F greatly strengthened mechanical reduced their sensitivity. summary, core‐shelled prepared strategy possessed 5‐in‐1 properties, which provided a new idea for targeted modulation energetic materials.

Single Cu Atoms Anchored Energetic COFs as Combustion Catalytic Promoters toward Rapid and Concentrated Thermal Decomposition of Ammonium Perchlorate

Abstract Achieving a synergistic, rapid, and concentrated energy release process of ammonium perchlorate (AP) is vital significance for boosting the thrust composite solid propellants. However, conventional catalytic promoters often exhibit suboptimal kinetics due to inefficient utilization active sites. Herein, atomically dispersed Cu‐coordinated covalent organic frameworks (COFs)‐based are reported, decorating with energetic anion groups. The highly accessible single Cu sites confined in COFs significantly contribute raid AP, yielding sharply narrowed decomposition peak at 341.3 °C width only 9 °C. This performance markedly superior exothermic raw AP (410.3 30 °C). Additionally, COF promoter considerably increased output via collaboratively promoting chemical its own decomposition. Correlating situ spectroscopies theoretical calculations reveals that incorporated anionic groups effectively modulate local electronic structure alteration promotes key step cleavage Cl─O bonds intermediates produce reactive oxygen species also boosts oxidation NH 3 high‐valence nitrogen oxides, thereby accelerating combustion reaction kinetic.
