Abstract

The invention discloses an energetic composite material based on a three-dimensional ordered macroporous carbon skeleton and a preparation method of the energetic composite material and belongs to the field of energetic materials. The preparation method comprises the following steps: dissolving an energetic material in a volatile organic solvent at room temperature to obtain a solution, impregnating a three-dimensional ordered macroporous carbon skeleton material in the solution and after the solvent is completely volatilized, loading the energetic material in a form of nanometer crystals inside the three-dimensional ordered macroporous carbon skeleton to obtain the performance-adjustable nanometer composite energetic material. By the preparation method, the energetic material can be stabilized on the nanometer scale and a novel idea is provided for designing a performance-adjustable high-energy-density energetic material. The thermal performance of the obtained nanometer energetic composite material is significantly improved, the thermal decomposition peak temperature is obviously decreased, the energy is rapidly released and the energetic composite material has wide application prospects in the nanocrystallization of the energetic materials and controllable energy-release and micro-energetic devices.

Description

technical field [0001] Embodiments of the present invention relate to the field of energetic materials, and more specifically, embodiments of the present invention relate to an energetic composite material based on a three-dimensional ordered macroporous carbon skeleton and a preparation method thereof. Background technique [0002] Energetic materials, mainly including explosives, propellants and pyrotechnic agents, are multifunctional materials that have been widely used in military and civilian applications. Since most applications of energetic materials have clear requirements for their reactivity, designing energetic materials with controllable properties has always been a research hotspot in this field. In the early research, the purpose of regulating the reactivity of energetic materials can only be achieved by mixing different kinds of chemical substances. With the development of nanotechnology, it has been found that energetic materials are generally composed of or...
