To improve the safety of HMX, a two-dimensional (2D) graphene oxide (GO) was introduced to HMX by the solventnonsolvent method. The morphology, composition, thermal decomposition characteristic were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetry (TG) and differential scanning calorimetry (DSC). Compared to the previous reports, GO sheets exhibited better desensitizing effect than [60]Fullerene and CNTs. When 2.0wt-% GO sheets were added, the impact sensitivity of raw HMX decreased from 100 to 10%, and the friction sensitivity reduced from 100 to 32%. The DSC results proved that GO sheets were compatible with HMX. In addition, by determining the thermal decomposition kinetic parameters of the samples, it was found that the activation energy (E-a) of HMX with 2.0wt-% GO increased by 23.5kJ mol(-1), suggesting that GO sheets could improve the thermal stability of HMX.
