Abstract
Herein, we report the large-scale preparation of graphene nanosheets via the deflagration of an obsoleted single base propellant in the presence of dibutyl phthalate (DBP) aiming at decreasing the oxygen balance. The high ambient pressure and high temperature generated during the deflagration process provided sufficient conditions for the efficient formation of carbon atoms and the subsequent shaping of graphene nanosheets. The prepared graphene nanosheets were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, and X-ray diffraction (XRD). This simple method is promising for future large-scale and cost-effective production of graphene nanosheets, as well as for the disposal of obsoleted energetic materials.
