Highly transparent polyethylene terephthalate (PET) mesh fabrics were dip coated with carbon nanotubes (CNT) followed by inkjet printing with poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) to develop textile-based CNT/PEDOT:PSS composite conductors. These coated fabrics show a combination of conductivity, transparency and flexibility suitable for use in flexible displays. Sequential CNT and PEDOT:PSS coating greatly enhances the conductivity at high tensile strains without reducing the optical transparency. Electroluminescent (EL) devices using such textile-based CNT/PEDOT:PSS composite conductors as the front electrodes exhibit superior flexibility and mechanical robustness over their ITO-coated PET film-based counterparts under stretching and tight bending. © The Royal Society of Chemistry 2012.
