Abstract

Carbon material has been designed as substrate to improve the sensitivity characteristics of copper azide (Cu(N3)2), lots of research findings have supported this strategy. However, the thermal decomposition mechanism of Cu(N3)2 nanocomposite has not yet been revealed. In this work, graphene was used as a composite material to prepare a Cu(N3)2/graphene composite primary explosive. Differential scanning calorimeter (DSC) and thermogravimetric-infrared spectroscopy (TG-DSC-FTIR) were used to analyse its thermal decomposition performance. The results showed that the composite of graphene could delay the decomposition point of Cu(N3)2 to 215.49 °C, indicating that the heat release of composite copper azide was concentrated, and the thermal decomposition rate was accelerated. The thermal decomposition reaction kinetic results indicated that the thermal decomposition of Cu(N3)2/graphene accord with the Avrami–Erofeev equation (No. 11 Mechanism Function), and its Apparent Activation Energy (Ea) was 113.42 kJ/mol, and the exponential factor log A was 9.26 s−1.
