| Abstract: | This paper presents a detailed study on the properties of different polymer inks based on poly(3,4ethylenedioxythiophene)/polystyrenesulfonate
regarding their processability in an experimental piezo driven drop-on-demand (DoD) micro-feeding system. Based on the rheological
properties of the used inks and the mechanical properties of the printing system characteristic values are derived which allow
to predict the processability of polymer inks in a given printing system. Beside the printability the influence of different
polymer inks on the electrical characteristics of printed organic field effect transistors is investigated. |
