Abstract
Devices, systems, and methods related to a transparent conductive film are disclosed. In one aspect, a method of forming a transparent conductive member (e.g., a transparent conductive film) includes extruding a metallic nanoparticle composition from a capillary tube onto a temporary substrate to form an extrudate. The extrudate can include metallic nanoparticle lines. The method further includes sintering the extrudate and the temporary substrate, dispensing a photocurable polymer onto the temporary substrate, and laminating a second substrate to the photocurable polymer. The photocurable polymer and the extrudate are interposed between the temporary substrate and the second substrate. The method further includes curing the photocurable polymer to form a transparent polymer layer and separating the temporary substrate from the transparent layer to form the transparent conductive member. The transparent conductive member includes the transparent polymer layer and the extrudate embedded in the transparent polymer layer.
