Decomposition of Ammonium-Perchlorate-Encapsulated Nanoscale and Micron-Scale Catalyst Particles

Carbon Fibers Enhance the Propagation of High Loading Nanothermites: In Situ Observation of Microscopic Combustion

“…One approach for balancing the mechanical integrity, potential energy density, and energy release rate could be to incorporate additives. For example, replacing conventional binders with energetic ones ,− or applying the catalyst embedded with ammonium perchlorate. , Embedding reactive or metal wires is known to promote combustion. − New techniques and formulations have been introduced to increase the energetic material content , and control combustion behavior via alterations to the chemical content. , However, since these materials largely rely on nanothermites as their primary energetic component to maximize energy release, it is possible that energy is being inefficiently coupled back into the system to promote propagation, given their longer reaction time . Considering that energy release rates in propellants are determined by how fast reactions occur and how fast energy can be transferred to unreacted material, one could feasibly use thermally conductive materials as a method to improve the heat transfer and energy release rate .…”
