In this investigation, we successfully synthesized a hybrid material, N‐rGO@Fe2O3, via a one‐step hydrothermal process, comprising nitrogen‐doped reduced graphene oxide and α‐Fe2O3. Thorough characterization using diverse analytical methods validated its structure. Employing this hybrid composite as a catalyst, we studied its efficacy in the catalytic thermal decomposition of ammonium nitrate (AN). The N‐rGO@Fe2O3/AN composite was prepared using a recurrent spray coating method with 3 % mass of the hybrid material. Thermo‐gravimetric (TG) and differential scanning calorimetric (DSC) analyses were employed to investigate the catalytic effect. Computational assessment of Arrhenius parameters was conducted through isoconversional kinetic approaches. Results from the kinetic analysis allowed the determination of the critical ignition temperature. Furthermore, calorific values for pure AN and N‐rGO@Fe2O3/AN were measured using an oxygen calorimetric bombe, revealing a 41 % reduction in activation energy barrier and a lowering of the critical ignition temperature from 292 °C to 283 °C upon incorporation of the hybrid material. Notably, the surface modification of AN with N‐rGO@Fe2O3 resulted in an increase of 1440 J/g in the observed calorific values. These findings highlight the potential of N‐rGO@Fe2O3 as an effective catalyst, offering promising implications for applications in enhancing ammonium nitrate thermal decomposition.

Hydroxyl Terminated Poly Butadiene (HTPB) based polyurethanes are widely used as polymeric binders in energetic formulations & other applications. Hence, customization in structure of HTPB has been investigated to improve their mechanical and thermal properties. Herein, modification of HTPB polyurethane has been reported in this paper by incorporating 2-hydroxy-3, 5-dinitropyridine (DNP) covalently into the HTPB polyurethane matrix in order to exhibit selfhealing properties. The functionalized polyurethane concurrently displays self-healing capability via metal-ligand interac-tion and also catalytic activity towards thermal decomposition of Ammonium Perchlorate (AP). The self-healing ability was observed by Optical Microscope and up to 96 % healing efficiency was observed by UTM analysis. Further, the catalytic activity was observed with thermal decomposition of Ammonium Perchlorate performed by DSC shows lowering in decomposition temperature by 73 °C. By involving the selfhealing and catalytic activity through single moiety in the polymer chain, this two-in-one strategy allows to produce advance binders for energetic formulations.

“…And carbon materials have been widely utilized to reduce the sensitivity for their unique structure and excellent physical and chemical properties [6,[25][26][27]. Compared with other carbon materials, graphene oxide (GO) has presented as a competitive candidate for coating material due to its excellent hydrophilicity and excellent electrical, mechanical and thermal properties [28][29][30][31][32]. Unfortunately, the nitro group of explosive and carboxyl group of GO both endows these two materials with negative charge respectively.…”

Inspired by the better desensitizing effect introduced by enhanced interaction, ammonium formate (Am) was utilized to modify graphene oxide (GO) and the functional graphene oxide (Am−GO) was obtained in this work, which was endowed with more amino groups and completely positive charge. Due to the modification and corresponding enhanced interaction, the impact sensitivity and friction sensitivity of HMX/Am−GO can be desensitized to 40 J and 192 N, respectively. To further desensitize the friction sensitivity, graphite (G) was utilized to replace part of Am−GO. And HMX/Am−GO/G was endowed with 40 J and 360 N of impact sensitivity and friction sensitivity respectively, which is the best desensitizing effect of HMX to our best knowledge. Furthermore, CL‐20 and DNTF were coated by the same coating, which also can be desensitized with the best effect. In addition, because the coating process is performed in water at room temperature, this desensitization is environment‐friendly and benefit for the large scale of production. This work demonstrates the improved desensitizing effect with enhanced interaction and provides a potential general applicable method for desensitization.
