54.2: Direct Printed Electrodes of Transparent Conductive Polymers for Flexible Electronic Papers

Direct formation of line-shaped electrodes consisting of transparent conductive polymer of poly(3, 4-ethylene dioxythiophene) and poly(styrenesulfonate) (PEDOT/PSS) was successfully achieved onto a flexible polyethylene terephthalate (PET) substrate by using screen printing method. Improvement of the components and the viscosity of the conductive materials enabled to pattern the line electrodes in high resolution. A 4.0 in. diagonal and 88 dpi flexible electronic paper display using quick response liquid-powder technology has been prepared by applying the flexible substrate with the direct printed transparent polymer electrodes.
