Abstract
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is a primary candidate for the conductive material in printable electronics. Currently, lateral resolutions down to only 30 μm have been demonstrated for roll-to-roll (R2R)-compatible PEDOT:PSS printing. However, increasing lateral resolution of the printing technique can increase the complexity/ability of printed devices. Topographical discontinuous dewetting (TDD) and liquid-bridge transfer (LBT) is employed as a high-resolution, scalable, R2R-compatible patterning technique to fabricate PEDOT:PSS patterns with down to 400 nm lateral resolution and high thicknesses. PEDOT:PSS ink dispersions were prepared with water/ethano..
