Abstract

The graphene aerogel/ ammonium nitrate (GA/AN) nano composite energetic material was prepared by the sol-gel method and supercritical CO₂ drying method. The morphology and structure of GA/AN nano composite energetic material were characterized by elemental analysis (EA), scanning electron microscope (SEM), nitrogen sorption tests and X-ray diffraction (XRD). The thermal decomposition behavior was investigated by TG and DSC. The results show that AN exists by nano size in the GA with an average particle size of 71nm, mass fraction of 92.71%. GA exhibits the promoting effects in the thermal decomposition process of AN. Compared to pure AN, the decomposition peak temperature of GA/AN nano composite energetic material decreases by 33.68℃ and the apparent heat of decomposition increases by 532.78J/g.
