Nanoenergetic Materials have a broad area of development that is rapidly growing and has emerging applications in many areas, including high-power linear actuators, solid fuels micropropulsion systems, and biocidal agent defeat formulations. These nanomaterials are produced at the heterogeneous form, and typically, their reactions are highly exothermic. The use of nanostructured particles instead of microparticles increases the intimate contact between the fuel and oxidizer, which decreases mass transport limitations and increases the reaction rate and reactivity of the energetic formulations. Thermodynamic calculations of the nanoenergetic reactions revealed maximum adiabatic temperature up to 3,827 K. This article describes the development and principles of novel nanoenergetic systems comprising high pressure-volume (PV) values and energy densities.
