Fabrication of flexible transparent electrodes using PEDOT:PSS and application to resistive touch screen panels

ABSTRACT The flexible transparent electrodes were fabricated by line patterning of conductive inks consisting of poly(3,4‐ethylenedioxythiophene) doped with poly(4‐styrenesulfonic acid) (PEDOT:PSS) water dispersion, ethylene glycol, isopropyl alcohol, and tetraethoxysilane (TEOS) on polyethylene ter...

Description
Summary:ABSTRACT The flexible transparent electrodes were fabricated by line patterning of conductive inks consisting of poly(3,4‐ethylenedioxythiophene) doped with poly(4‐styrenesulfonic acid) (PEDOT:PSS) water dispersion, ethylene glycol, isopropyl alcohol, and tetraethoxysilane (TEOS) on polyethylene terephthalate (PET) films. The values of sheet resistance (Rs), total light transmittance, haze, figure‐of‐merit, and pencil hardness of the PEDOT:PSS‐TEOS/PET film were found to be 301 Ω/sq., 85.0%, 2.4%, 41, and 2H, respectively. Furthermore, a resistive touch screen panel was fabricated using the PEDOT:PSS‐TEOS/PET film as the top electrode. It was found that the drawing on the resistive touch screen panel was successfully displayed on the PC screen with good in‐plane uniformity and maximum linearity of 0.8%. © 2017 Wiley Periodicals, Inc.
