Bioinspired tea polyphenols modification of energetic crystals with reduced impact sensitivity and enhanced thermal stability

Abstract

TP has similar advantages to dopamine and can form hydrogen bonds with energetic materials, enhancing interfacial interactions and achieving desensitization. In this study, RDX@TP and HNIW@TP were successfully prepared using TP as desensitized shells. The results indicated that the thermal decomposition temperature of RDX@TP and HNIW@TP increased by 4.4℃ and 11℃ respectively. Moreover, the impact sensitivity of RDX@TP and HNIW@TP decreased by 1.63 times and 2 times respectively. These findings demonstrate the successful application of TP as desensitized shells in energetic materials.
