Polymer light emitting diodes (PLED) were prepared by soft lithography techniques based on elastomer stamps. Conducting poly(3,4-ethylenedioxythiophene) (PEDOT) and poly(styrene sulfonate) (PSS) made up the conducting polymer complex PEDOT-PSS. The conductivity in a PEDOT-PSS film was ≈1 S/cm using a common thickness of 80-200 nm. The addition of glycerol increased the conductivity by two orders of magnitude after thermally evaporating off the glycerol content in the film. The PEDOT-PSS lines produced by microcontact printing showed an edge roughness of 1-2 μm. The width of the smallest lines was 100 μm. The smallest lines formed by the lift-up method were 10 μm wide.
