Patterning of Conductive Polymer Anodes Using a Peel-off Method

Here we report another soft lithography, peel-off method, for patterning conductive polymer anodes in the fabrication of flexible ITO-free organic light-emitting diodes. This method doesn't require any heating process and UV light. We have demonstrated that such a peel-off technique enables the formation of a very sharp edge and the enhancement of edge roughness.
