The booming development of DIW technology present an unprecedented prospect in energetic materials field and has attracted great interest due to its relative simplicity and high flexibility of manufacturing. Herein, a novel CL-20 based explosive ink formulation have been developed successfully for MEMS initiation systems via DIW technology. We designed PVA/GAP into an oil-in-water(O/W)emulsion, in the way that the aqueous solution of PVA as water phase, the ethyl acetate solution of GAP as oil phase, the combination of Tween 80 and SDS as emulsifier, BPS as a curing agent of GAP. The ideal formulation with good shear-thinning rheology properties and clear gel point was prepared using only 10 wt% emulsion. The dual-cured network formed during the curing process made the printed sample have good mechanical properties. The printed samples had satisfactory molding effect without cracks or fractures, the crystal form of CL-20 not changed and the thermal stability have improved. Deposition of explosive inks via DIW in micro-scale grooves had excellent detonation performances, which critical detonation size was 1 × 0.045 mm, detonation velocity was 7129 m/s and when the corner reaching 150° can still detonated stably. This study may open new avenues for developing binder systems in explosive ink formulations.

DIW技术的蓬勃发展在含能材料领域呈现出前所未有的前景，并因其相对简单和制造的高度灵活性而引起了人们的极大兴趣。在此，一种基于 CL-20 的新型爆炸墨水配方已通过 DIW 技术成功开发用于 MEMS 启动系统。我们将PVA/GAP设计成水包油(O/W)乳液，以PVA水溶液为水相，GAP乙酸乙酯溶液为油相，Tween 80与SDS结合为乳化剂，BPS作为GAP的固化剂。仅使用 10 wt% 的乳液即可制备出具有良好剪切稀化流变性和清晰凝胶点的理想配方。固化过程中形成的双重固化网络使打印的样品具有良好的力学性能。打印出来的样品成型效果满意，无裂纹或断裂，CL-20晶型不变，热稳定性有所提高。DIW在微槽中沉积炸药油墨具有优异的爆轰性能，临界爆轰尺寸为1×0.045 mm，爆速为7129 m/s，当转角达到150°时仍能稳定起爆。这项研究可能为在爆炸性油墨配方中开发粘合剂系统开辟新途径。爆速为7129 m/s，当转角达到150°时仍能稳定起爆。这项研究可能为在爆炸性油墨配方中开发粘合剂系统开辟新途径。爆速为7129 m/s，当转角达到150°时仍能稳定起爆。这项研究可能为在爆炸性油墨配方中开发粘合剂系统开辟新途径。
