Abstract

Flexible transparent electrodes were fabricated by line patterning of conductive inks consisting of poly(3,4-ethylenedioxythiophene) doped with poly(4-styrenesulfonate) (PEDOT/PSS) and ethylene glycol on PET films. The average values of thickness, sheet resistance (R_s), electrical conductivity, total light transmittance (TT), and haze of the flexible transparent electrodes in the range of PEDOT/PSS dispersion between 80~95 wt% were found to be 101 nm, 160 Ω/□, 630 S/cm, 95.5% and 1.3%, respectively. The standard deviations of in-plane distributions of R_s (av. 146 Ω/□) and TT (av. 93.5%) were 3.9 Ω/□ and 0.2%, respectively, indicating high uniformity with excellent electrical and optical properties as flexible transparent electrodes. Furthermore, a polymer dispersed liquid crystal (PDLC) display was fabricated using the flexible PEDOT/PSS transparent electrodes. It was found that the PDLC display successfully operated by the opaque/transparent change due to the scattering/non-scattering transition caused by the electric field applied through top and bottom PEDOT/PSS electrodes.
