![]() ![]() Moreover, a model-free approach is applied to a differential scanning calorimetry (DSC) data to evaluate the kinetic triplet of the reduction mechanism. The results demonstrate the successful reduction of the graphene oxide film (GOF), leading to a prominent electrical conductivity (3275 S m−1). The structural, the morphological, and the electrical properties of the as-prepared films are scrutinized via a series of characterization techniques. This study introduces a straightforward and cost-effective route to elaborate a thermally reduced graphene oxide film (R-GOF) at 350 ☌ under ambient atmosphere, followed by the investigation of the kinetic triplet of the related thermal reduction mechanism by a model-free approach. This technology is expected to provide new ideas for designing and preparing solid propellants with high energy, low susceptibility, and excellent thermal decomposition performance. ![]() The insensitive shell layer HNS significantly improves the safety performance of AP through barrier and buffering effects. The safety performance test shows that the nano-HNS with 15% mass content can increase the composite characteristic drop height H 50 to 32 cm and reduce the frictional susceptibility explosion probability to 77% (the H 50 of AP is 27 cm and the frictional susceptibility explosion probability is 95%). The results show that the composites have a complete and dense shell structure when the nano-HNS content of the shell layer is 15% or more, the synergistic decomposition effect between HNS and AP can advance the high-temperature decomposition peak of AP by 102.4 ☌ and increase the apparent heat release 2.55 times to 1388 J g-1, and HNS improves the energy of AP while reducing environmental pollution. In this paper, (hexanitrostilbene) composites with core-shell structure were designed and prepared by an ultrasound-assisted method using polyurethane for the interfacial modification of ammonium perchlorate (AP). Solid propellants with high safety, excellent thermal decomposition, and green performance are hot and difficult research areas in aerospace. ![]()
