摘要: Abstract Fast patterning of highly conductive polymers like PEDOT:PSS (poly (3,4-ethylene dioxythiophene): polystyrene sulfonate) with lasers can contribute to the development industrial production liquid crystal displays on polymer foils. In this article, selective UV laser a film flexible films is investigated. Based their optical properties, three are investigated: polyethylene terephthalate (PET), polymethyl methacrylate (PMMA) and cellulose triacetate (TAC). Ablation parameters for 110 nm these optimized. A detailed study crater depth, topography surface composition provided using profilometry, scanning electron microscopy (SEM) X-ray photoelectron spectroscopy (XPS), respectively. The electrical insulation lines measured correlated analyses different settings. Finally, potential ablation each derived.
