Abstract
Processes for producing and treating thin-films comprising nanomaterials are provided. A process of producing a transparent conducting film includes printing nanomaterials on a substrate, and directing a laser beam onto the nanomaterials to weld junctions between the nanomaterials. A process for tightly integrating nanomaterials with 2D material includes locating the 2D material over the nanomaterials, and directing a laser beam towards the 2D material to produce laser shock pressure sufficient to wrap the 2D material on the nanomaterials. A process of reducing the resistivity of a transparent conducting film includes directing a first laser beam towards a transparent conducting film having nanomaterials thereon such that the nanomaterials experience laser shock pressure sufficient to compress the nanomaterials, and then directing a second laser beam towards the transparent conducting film such that junctions between the nanomaterials are fused.
