Nano-composite energetic materials,hexahydro-1,3,5-trinitro-1,3,5-triazine/resorcinol-formaldehyde(RDX/RF) aerogel,was prepared by crystallization of RDX in the N,N-dimethyllformamide(DMF) within the nano-dimensional pores of resorcinol-formaldehyde(RF) gel matrix.The structures of RDX/RF aerogel were characterized by atomic force microscopy(AFM),scanning electron microscopy(SEM),X-ray powder diffraction(XRD),and BET method.Experimental results show that the grid size formed by RF ranges from several to several decade nm and the mean size of nano-RDX in RDX/RF is 38 nm.The specific surface area for RF aerogel is 551.5 m~2·g~(-1),and for RDX/RF aerogel is 142.7 m~2·g~(-1).Compared to the corresponding values of the mechanical mixtures with the same components,the exothermic peak of RDX/RF aerogel moves down about 25 ℃,and the mechanical(sensitivity) decreases a little.
