Electric Field of the Tip-Plane Electrode Configuration in Electrohydrodynamic Printing

Abstract:

Electrohydrodynamic printing draws much attention as it is a promising micro/nano patterning method and can ejects high-viscosity solution. The solution is pulled out of a nozzle under a high voltage. A used tip-plane electrode configuration is composed of a conducting plane collector and a hyperbola-shaped solution pendant adhered to a steel nozzle in electrohydrodynamic printing. The electric field between electrodes is extremely non-uniform owing to structural complexity of electrode configuration. We disintegrate the overall electric field into three components: a charge-free space field, a charged droplet field and an ion field. Proper models for those fields are set up and analyzed. The result shows that the elliptic-cylinder model, a dominant component for the jetting, is available for the field. The charged droplet field hardly deforms the space field in low-frequency pulsation mode, but influences the jetting in high-frequency pulsation mode. The ion field caused by space ions is little and negligible.
