In order to improve the catalytic activity of graphene oxide (GO) on the thermal decomposition of ammonium perchlorate (AP), a novel energetic functionalized graphene oxide (EFGO) was prepared by GO and 2, 4, 6-trinitroaniline (TNA) as raw materials, N, N-dimethylformamide and triethylamine as the solvent and acid binding agent. Its structure was characterized by HRTEM, Raman, FT-IR and XPS. The thermal decomposition behavior of EFGO and its catalytic effect on the thermal decomposition of AP were analyzed and investieated by TG-DTG and DSC. The results showed that TNA was grafted to the surface of the GO sheet by covalent bond. The-NH2 in the TNA molecule reacted with the epoxy group on the surface of the GO sheet to form a C-NH bond. EFGO had high thermal stability, and a very slow mass loss process occurred in the range of 143.8-770.0℃. The maximum mass loss rate occurred at about 172.1℃ and the whole mass loss was 21.2%. When the contents of EFGO in AP mixtures were 2.5%, 5% and 10% respectively, the exothermic peak temperatures of AP in the high temperature decomposition stage decrease by 25.6, 48.0 and 113.1℃, the overall heat of AP increase by 371, 1499 and 2693J/g, respectively. It indicated that EFGO has a better catalytic effect on the thermal decomposition of AP compared to GO, and it has a potential application as a metal free energetic catalyst in the AP-based solid propellants. © 2020, Editorial Board of Journal of Explosives & Propellants.
