Abstract

Over the past two decades there has been significant growth in our understanding of nanothermites and other nanoenergetic material. However, there is still much that is unknown about the physics and processes that control these highly exothermic reactions. In this chapter, we provide an overview of the three main components to the combustion of aluminum nanoparticle-based energetics: heat transfer mechanism, effect of the oxide shell, and reaction pathway. Each section contains a discussion of the general theories and processes involved, as well as the latest evidence. Combining all the ideas and most likely mechanisms, we finally discuss how an understanding of these mechanisms can shape and guide the future development of nanoenergetic materials.
