Preparation of TATB-BTF Nanocomposite Energetic Materials Using Solvent Vaporizing Method
The preparation of nanocomposite energetic materials is currently a very active and exciting research area. In this paper, TATB-BTF composite particles were prepared through solvent vaporizing method, also the composite particles structure, thermal performance and mechanic sensitivity were characterized by scanning electron microscopy(SEM), differential scanning calorimetric(DSC) and impact sensitivity experiment. The SEM images revealed that most TATB-BTF composite particles were around 200nm in diameter, these nanocomposite particles did not show visible shape change and particles size distribution became narrower and smaller compared with the original ultrafine TATB particles whose size was around 400nm. These evidence indicated that ultrafine TATB aggregations were broken up and dispersed during the vaporization of solvent and construction of nanocomposite. The thermal decomposition experiments showed that thermal decomposition peaks of both two components forming TATB-BTF composite appeared on DSC curves. The impact sensitivity of TATB-BTF nanocomposite were significantly reduced compared with that of the physical mixture although their composition and ratio were the same.
