摘　　要：基于电流体力学的微喷印技术是一种可用于制造微纳米结构及器件的新型印刷电子技术。本研究首先讨论了微喷印系统喷嘴尖端的泰勒锥弯液面分别在直流偏压和脉冲电压与直流偏压叠加作用下的受力情况,推知作用在弯液面的电场切向应力比电场法向应力增长快,电场切向应力对射流的形成有助"推"作用。其次重点考察脉冲电压频率与射流液滴间隔、液滴喷射频率、液滴直径的关系,并将理论结果与实验结果进行比较分析。最后通过分析得出,在一定条件下,合理控制脉冲频率可以获得具有相同液滴间距和所需尺寸的液滴。The micro -jet printing technology based on Electrohydrodynamics is a new method of printed electronics technol- ogy for manufacturing micro/nano structures and devices. In this study, firstly, stresses that Taylor cone meniscus suffered under DC bias voltage and pulse voltage overlayed on DC bias voltage in micro -jet printing system based on EHD were dis- cussed respectively, and the results showed that tangential electric stress grew faster than normal electric stress which applied on the meniscus and tangential electric stress helped to ＂push＂ jet generation. Secondly, the correlations of pulse frequency and droplet spacing, droplet ejecting frequency, droplet diameter separately were emphasized, and then the theoretic results werecompared and analyzed with the experimental ones. Finally, it was concluded that droplets with almost the same interval and desired size could be obtained on the certain situation through controlling pulse frequency properly
