Abstract

The invention discloses a two-dimensional energetic material, and at least one of an oxidizing agent component and a fuel component is a graphene two-dimensional material, and is prepared into a two-dimensional nanosheet. The oxidizing agent component is MoO3 or MnO2, the content of the oxidizing agent component is 10%-90%, the fuel component is one of Al, Mg, B, Ti, Si or P, and the content of the fuel component is 10%-90%. The two-dimensional material and the nanometer energetic material are perfectly combined together, the problems of poor dispersity, easiness in aggregation of particles, poor instantaneous heat release of the nanometer energetic material are solved, and the application of the two-dimensional nanomaterial is also expanded.

Description

technical field [0001] The invention relates to the field of novel composite energetic materials, in particular to a two-dimensional energetic material and a preparation method thereof. Background technique [0002] Energetic materials refer to single-substance compounds or mixtures that contain explosive groups or are composed of oxidizers and combustion agents, and can independently undergo chemical reactions, burn or explode, and output energy. Among them, composite energetic materials are the most diverse and powerful, and have been extensively studied. At present, researchers of composite energetic materials have been devoting themselves to developing new formulations of energetic materials to increase the rate of energy release, thereby enhancing the power of composite energetic materials. Among the many methods to improve the power of composite energetic materials, refining the particle size of fuel components and oxidant components that make up composite energetic m...
