Abstract

The behavior of nanoscale energetic materials is quite different from micronsized energetic materials in many ways. Recently, some techniques such as sol-gel method, high speed air impaction and vacuum codeposition have been employed to obtain nanoscale energetic materials. However, only few attentions were paid to nanoscale energetic materials because of the fabrication difficulty. In this paper, the simple preparation of a nitramine 2,4,6,8,10,12 hexanitro 2,4,6,8,10,12 hexaazaiso wurtzitane (HNIW) with nanometer size by microemulsion method is presented. The microemulsion systems contained tween80, 2-propanol and n-butyl acetate as the oil phase. On the base of DLS measurement average particle size is 8 nm. The prepared nanoparticles are semispherical based on SEM picture.
