Abstract:
      Nanothermites energetic materials have been widely used in various fields due to their large specific surface area, high volume energy density, and high reaction rate. In order to achieve uniform mixing and performance changes among the components of nanothermites, various forms of preparation methods have been developed. With the diversification of applications of nanothermites, their storage performance during long-term storage needs further observation to prevent their failure or accidental ignition under environmental or other stress conditions. Therefore, it is necessary to conduct research on the preparation methods and aging performance of nanothermites during storage. Preparation methods and aging research of nanothermites are summarized, including advantages and disadvantages of preparation methods, aging methods, performance evaluation, mechanism research, and inhibition measures of aging research, so as to provide reference for the application of nanothermite and further optimize the preparation methods and aging research.
