The production of energetic crystalized micro-patterns by using one-step printing has become a recent trend in energetic materials engineering. We report a direct ink writing (DIW) approach in which micro-scale energetic composites composed of 1,3,5-trinitro-1,3,5-triazinane (RDX) crystals in selected ink formulations of a cellulose acetate butyrate (CAB) matrix are produced based on a direct phase transformation from organic, solvent-based, all-liquid ink. Using the formulated RDX ink and the DIW method, we printed crystalized RDX micro-patterns of various sizes and shapes on silicon wafers. The crystalized RDX micro-patterns contained single crystals on pristine Si wafers while the micro-patterns containing dendrite crystals were produced on UV-ozone (UVO)-treated Si wafers. The printing method and the formulated all-liquid ink make up a simple route for designing and printing energetic micro-patterns for micro-electromechanical systems.
通过一步印刷制备高能结晶微图案已成为含能材料工程领域的最新趋势。我们报道了一种直接墨水书写（DIW）方法，基于从有机、溶剂基全液体墨水的直接相变，在醋酸丁酸纤维素（CAB）基质的选定墨水配方中制备由1,3,5-三硝基-1,3,5-三嗪烷（RDX）晶体组成的微尺度含能复合材料。使用配制的RDX墨水和DIW方法，我们在硅片上印刷了各种尺寸和形状的结晶RDX微图案。在原始硅片上，结晶的RDX微图案包含单晶，而在经紫外线臭氧（UVO）处理的硅片上制备了包含枝晶的微图案。该印刷方法和配制的全液体墨水为微机电系统设计和印刷含能微图案提供了一条简单途径。
