Producing transparent conductive layer, by applying dispersion from transparent conductive oxide nanoparticles on substrate e.g. glass, and partially removing solvent/dispersant from obtained layer and then irradiating with laser energy

摘要

The method comprises applying a dispersion from transparent conductive oxide (TCO) nanoparticles on a substrate such as glass or plastic, partially removing solvent or dispersant from the obtained layer by drying at 20-180[deg] C for a time period of 1 second to 60 minutes, and subsequently irradiating the obtained layer with a laser energy uniquely by scanning in a continuous or pulsed manner and then subjecting to a plasma treatment. The dispersion contains indium-tin oxide nanoparticles and is applied on the substrate by inkjet-printings, flexographic printings and pad-printings.

The dispersion contains indium-tin oxide nanoparticles and is applied on the substrate by inkjet-printings, flexographic printings, pad-printings, spin coating, spraying, dipping, knife-coating, offset printings, screen printings, thermo-transfer printings, gravure printings, flooding, aerosol jet deposition process or pouring. The laser energy has a wavelength of 157-10600 nm with an average output of 5 W to 5 kW, and affects the material of the layer in the sectioned volumes of the focused laser beam with the layer during a duration of 5 ps to 1000 mu s. During scanning, an intersection plane of the focused laser beam is moved with the plane of the layer on the intersection plane with a speed of 50-150000 mm/s. An independent claim is included for a transparent conductive layer.
