Abstract:

A simple and efficient method for patterning poly(3,4\|ethylenedioxythiophene)∶poly(styrene sulfonate) (PEDOT∶PSS) electrodes for application in the field of organic electronics was proposed. The entire PEDOT∶PSS layer, except  the desired pattern, was selectively detached from a flat substrate surface by an epoxy resin mold with a relief pattern.  Epoxy mold has a high  work of adhesion with polymer could make selective detachment occurrence, thereby the thin films can be rapidly patterned with large area.

Key words: poly(3,4-ethylenedioxythiophene)∶poly(styrene sulfonate) (PEDOT∶PSS) electrodes, organic field\, effect transistors; , epoxy resin mold; , micropattern; , selective detachment
