An electrohydrodynamic (EHD) printing method with nanosilver ink for flexible electronics
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 to . The air supply of resulted an obviously larger width than that of , but the printing process was unstable on the condition. The EHD printing was applied to realize nanosilver ink line ranged from to 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.
