ABSTRACT In this work, we reported nano-sensitized dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50) with micro/nano hierarchical structures were prepared by combined with ball milling and drying technology. The samples were characterized and the results demonstrated that nano sensitized TKX-50 possessed hierarchical network-like framework microstructures composed of TKX-50 nanoparticle units with the sizes of 100 ~ 300 nm. The formation mechanism of micro/nano hierarchical structures was proposed based on the self-assembly of liquid medium evaporation-induced agglomeration in the drying process. In addition, impact sensitivity evaluation showed that the impact sensitivities (H50: 15.0 cm, explosion probability: 100%) of nano sensitized TKX-50 have more sensitive properties than raw TKX-50 (65 cm, 25%). This work can offer a new understanding for the ball milling nano-sized method in energetic materials.

液体介质蒸发诱导凝聚自组装敏化纳米二羟基铵 5,5'-双四唑-1,1'-二醇 (TKX-50)

摘要 在这项工作中，我们报道了结合球磨和干燥技术制备了具有微/纳米分级结构的纳米敏化二羟基铵 5,5'-双四唑-1,1'-二醇 (TKX-50)。对样品进行表征，结果表明纳米敏化TKX-50具有由100~300 nm大小的TKX-50纳米颗粒单元组成的分层网络状骨架微结构。基于液体介质在干燥过程中蒸发引起的团聚的自组装，提出了微/纳米分级结构的形成机制。此外，冲击敏感性评价表明，纳米敏化TKX-50的冲击敏感性（H50：15.0 cm，爆炸概率：100%）比原始TKX-50（65 cm，25%）具有更高的敏感性。
