In order to discover of high-energy materials with characteristics that surpass modern benchmarks, it is necessary study the widest range potential structures. The design energetic compounds using high-nitrogen cage scaffolds provides new opportunities. One promising representatives polycyclic multinitragen cages hexaazaisowurtzitane, since most powerful explosive CL-20 based on it. recent years, synthesis analogues has been actively developed. This review presents progress in synthesis, performance and structure-property relationship for polynitro hexaazaisowurtzitanes over past decade.

Abstract Aluminum powder is commonly used as a metal fuel additive in composite solid propellants. However, its tendency to agglomerate during combustion can lead two‐phase flow losses, negatively impacting energy performance. To address this issue and enhance the performance of aluminum powder, nitrated graphene oxide (NGO) was developed improve dispersion optimize characteristics. Various analytical techniques were employed examine properties, including Fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscopy (SEM), X‐ray photoelectron (XPS), elemental analysis (EA), differential calorimetry (DSC), thermogravimetric (TG). Al/NGO prepared using solution‐assisted method N, N‐dimethylformamide (DMF) characterized by SEM, XPS diffraction (XRD). The ignition characteristics heat measured laser igniter an oxygen bomb calorimetry. appropriate mass ratios NGO coating had positive effects on Al. Specially, 4 % reduced Al 46.5 increased efficiency 22.0 %. Moreover, catalytic effect thermal decomposition ammonium perchlorate (AP) investigated (DTA). Results showed that two‐stage pyrolysis paths AP tended merge into single process when added. most favorable AP′s produced with addition 10 , reducing activation Kissinger equation for high‐temperature 107.7 kJ mol −1 . These findings may provide valuable insight enhancing energetic materials through modification.
