Title: Methods of reducing ignition sensitivity of energetic materials

Abstract

An energetic material comprising an elemental fuel, an oxidizer or other element, and a carbon nanofiller or carbon fiber rods, where the carbon nanofiller or carbon fiber rods are substantially homogeneously dispersed in the energetic material. Methods of tailoring the electrostatic discharge sensitivity of an energetic material are also disclosed. Energetic materials including the elemental fuel, the oxidizer or other element, and an additive are also disclosed, as are methods of reducing ignition sensitivity of the energetic material including the additive. The additive is combined with the elemental fuel and a metal oxide to form the energetic material. The energetic material is heated at a slow rate to render inert the energetic material to ignition while the energetic material remains ignitable when heated at a fast rate.
