Energetic Materials and Combustion

Energetic materials—substances that store large amounts of chemical energy and release it rapidly through combustion or detonation—span a range of forms from conventional explosives and propellants to newer classes like ionic liquid salts and metal nanoparticles engineered at the nanoscale for tighter control over reactivity. Understanding how molecular structure, crystal packing, and thermal decomposition pathways determine performance and sensitivity requires both experimental characterization and computational tools such as ReaxFF-based molecular dynamics, which simulate bond-breaking events at atomic resolution without relying on predefined reaction mechanisms. A central challenge is designing high-energy density materials that maximize energy output while remaining stable enough to handle safely—a tradeoff that becomes especially complex in nanoenergetic systems, where surface-area-to-volume ratios alter ignition thresholds in ways bulk theory does not fully predict. Active research is pushing toward tunable formulations using ionic liquids and composite nanoparticle architectures, aiming to decouple sensitivity from performance in ways that legacy materials cannot achieve.
