Photoresist-Free Patterning by Mechanical Abrasion of Water-Soluble Lift-Off Resists and Bare Substrates: Toward Green Fabrication of Transparent Electrodes

Abstract: This paper describes the fabrication of transparent electrodes based on grids of copper microwires using a non-photolithographic process. The process—“abrasion lithography”—takes two forms. In the first implementation (Method I), a water-soluble commodity polymer film is abraded with a sharp tool, coated with a conductive film, and developed by immersion in water. Water dissolves the polymer film and lifts off the conductive film in the unabraded areas. In the second implementation (Method II), the substrate i… Show more

“…The crack‐onset strains were defined by the strain at which the first crack was observed by optical microscopy. The sheet resistance and conductivity of the films were measured by two‐terminal measurements as previously described . PEDOT:PSS films were prepared on FOTS‐treated glass as described above; films thickness were kept constant at ≈150 nm.…”

“…The sheet resistance (R s ) was calculated according to the relationship R s = R × (w/l), where w and l are the width and length of the TC region in the sample, respectively, and R is the electrical resistance obtained from two-probe measurements. 28,29 The electrical resistance was measured using a digital multimeter (U1253B, Agilent Technologies) capable of measuring up to 500 MΩ with a resolution of 0.01 MΩ. For the measurement, the probing electrodes at each end of the sample were electrically wired with a silver paste.…”
