Thermal behavior and explosive properties of TNT/RGO

Abstract

2,4,6-trinitrotoluene (TNT), is the most widely accessible explosive. Thanks to the melt cast characteristics (melting temperature of TNT is 80-82 °C,), lead to contribute in many applications as mortars, grenades, artillery rounds, warheads, and antipersonnel mines. TNT has high chemical stability, and moderate sensitivity. In this paper, a novel addition of nano particles of reduced graphene oxide (RGO) was added to enhance the TNT characteristics. A composite TNT/RGO 98:2 wt. % was prepared. The morphology of the composite mixture was captured using scanning electron microscopy (SEM). Impact sensitivity and friction sensitivity were evaluated, thermal behavior was investigated using diffeential scanning calorimetry (DSC), the characterization of the prepared composite and pure TNT was examined using an X-Ray diffractometer. Explosive characteristics were determined by detonation velocity and brisance by Kast . The results showed improvement in the sensitivity with reserving the high explosive characteristics of TNT. Interestingly, a decrease in the melting point of TNT due to the presence of RGO in the composite was observed. This addition might be an effective parameter in the melting procedure of TNT.
