Multifunctional 2D fluorinated coating and bioinspired interface on HMX for simultaneous desensitization and combustion enhancement
High sensitivity of energetic oxidizers and difficulties in activating passivated aluminum during the ignition are two serious obstacles for safe and efficient application of aluminized explosives. Herein, a safe and highly reactive HMX@PDA@FG (HPF) dual-shell oxidizer was constructed through functionalizing octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) core with a bio-enhanced interface polydopamine (PDA) and a two-dimensional (2D) fluorine source fluorinated graphene (FG) via bionic and self-assembly strategies. The synergistic integration of FG and PDA coatings achieves a remarkable reduction in HMX sensitivity (the impact energy increase from 7 to 28 J and friction load weight increase from 108 to 160 N). The 2D structure of FG notably enhances heat transfer within the system and leads to more rapid and concentrated decomposition of HMX. Furthermore, HPF oxidizers feature significant combustive activation effects for nano-aluminum due to high fluorine content of FG. Aluminized mixture HPF-10/n-Al exhibits superior combustion reactivity and energy output. The combustion heat of HPF-10/n-Al reaches 14,770.8 kJ/g, nearly 1000 kJ/g higher than HMX/n-Al, while the peak pressure and pressurization rate are approximately 1.5 and 4.9 times higher than HMX/n-Al. Hence, modifying multifunctional fluorinated graphene coating and bioinspired interface polydopamine on HMX shows great potential in enhancing both safety and energetic performance of aluminized explosives.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
