The particle size and morphology of explosive samples were characterized by scanning electron microscope, transmission electron microscope, and X-ray diffraction. The thermal decomposition properties and impact sensitivity of these samples were tested and analyzed. The results show that the RDX/GAP-ETPE microparticles are spherical in shape and range from 0.5 µm to 5 µm in size. In the microparticles, RDX particles uniformly and discretely disperse in GAP-ETPE binders with the particle size ranging from 50 nm to 200 nm. The thermal stability of RDX/GAP-ETPE nanocomposites is identical to raw RDX. The nanocomposite particles exhibit considerably low impact sensitivity, for its drop height is 73.6 cm, which increases by 50.3 cm compared with raw RDX.
