Repeated Duplication in EHD Line Patterning on a Non-Conductive Substrate Based on Controlling the Polarity of Applied Voltages

摘要

This paper presents an effective method of repeated duplications in EHD printing for forming a high aspect ratio of metal lines on a non-conductive substrate. As the number of repeated duplication increase, aspect ratio of metal lines increases. At the same time, but also increases the scattering of droplets around the patterned lines grows. To solve this problem, we proposed method is based on controlling of the polarity of the applied pulse voltages in such a way as to hinder the accumulation of charges, thus, reducing the scattering of droplets around the patterned line. It is verified experimentally that we can be reduce the scattering of droplets around the patterned line through the controlling of the polarity of the applied pulse voltages.
