Abstract
Energetic materials are the energy materials used by weaponry to accomplish launch, propulsion, and destruction. However, during manufacture, storage and use, they may be damaged and form microcracks when subjected to external stimuli such as temperature, humidity and impact, which ultimately lead to changes in material properties. Self-healing materials can repair the damage through physical or chemical processes, restoring their properties and extending their service life. This paper reviews the classification of self-healing polymer materials, principles underlying technologies for room-temperature self-healing polymer materials, and the applications of these technologies in energetic materials. Furthermore, this study proposes several key directions for future research on the technologies and their applications in energetic materials.
