In this paper, the electrohydrodynamic (EHD) printing method for the flexible electronics with nanosilver ink was studied. The effect of DC voltage and air pressure on the printed nanosilver line was experimentally researched on the printing system. The necessary working voltage was above 600 V DC voltage, and when the voltage reached 1100 V, the line width increased from [Formula: see text] to [Formula: see text]. The air supply of [Formula: see text] resulted an obviously larger width than that of [Formula: see text], but the printing process was unstable on the [Formula: see text] condition. The EHD printing was applied to realize nanosilver ink line ranged from [Formula: see text] to [Formula: see text] and a kind of antenna pattern for radio frequency identification devices (RFID) was fabricated. This kind of EHD printing method has the advantages of high flexibility and printing resolution and shows potential prospects in the field of flexible electronics.

一种用于柔性电子器件的纳米银墨水电流体动力学 (EHD) 打印方法

在本文中，研究了使用纳米银墨水的柔性电子产品的电流体动力学（EHD）印刷方法。在印刷系统上实验研究了直流电压和气压对印刷纳米银线的影响。所需的工作电压为600V以上的直流电压，当电压达到1100V时，线宽从[公式：见正文]增加到[公式：见正文]。[公式：见文]的送风导致宽度明显大于[公式：见文]的宽度，但在[公式：见文]条件下打印过程不稳定。应用EHD打印实现[公式：见正文]到[公式：见正文]的纳米银墨线，并制作了一种用于射频识别设备（RFID）的天线图案。
