Abstract

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.
