Mechanical Sensitivity Reduction of Energetic Materials by Using Carbon Nanomaterials

Abstract

Mechanical sensitivities (such as friction and impact sensitivity) are the most important evaluation index to characterize the risk of energetic materials (EMs), as they are the most common stimulus during preparation, transportation and usage of EMs. Recently, carbon nanomaterials (CNMs) have been found to be effective in reducing mechanical sensitivities of EMs with small amount of addition. This review covers updated researches of the desensitization of EMs by using fullerenes, expanded graphite (EG), carbon nanotubes (CNTs), graphene and graphene oxide (GO), their desensitization results and relative mechanisms are summarized. It has been shown that graphene and its derivatives are more effective due to their superior thermal conductivity and layered structure.
