- Abstract
- This paper presents a printing method to form a high-conductivity patterned poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) film. A modified PEDOT: PSS ink containing a secondary dopant (dimethyl sulfoxide) and fluorosurfactant (Zonyl FS-300) was inkjet-printed to form a uniform conducting layer, and the dimethyl sulfoxide, conductivity enhancer, was over-printed onto it to further enhance its conductivity. We achieved high-conductivity greater than 1000 S cm(-1) by only using inkjet-printing technique. The mechanism of conductivity enhancement was investigated with X-ray photoelectron spectroscopy and atomic force microscopy analyses. The printing process for high-conductivity PEDOT: PSS was applied to pattern a transparent anode for the fabrication of an organic light emitting diode. (C) 2016 Elsevier B.V. All rights reserved.
