Abstract
Disclosed is a transparent conductor. The transparent conductor comprises a transparent substrate, an adhesive layer and a conducting layer which are successively stacked. The conducting layer is a semi-solid transparent conductive photosensitive resin layer, and comprises a semi-solid transparent photosensitive resin matrix and nanometer conductive wires filling the semi-solid transparent photosensitive resin matrix. The nanometer conductive wires are connected in a staggered mode to form a conductive grid. According to the transparent conductor, the conducting layer realizes conduction through the conductive grid formed by staggered connection of the nanometer conductive wires, and compared to an ITO conducting layer, the conducting layer has relatively quite low resistance. The nanometer conductive wires are better in flexibility compared to ITO, such that the transparent conductor has quite good anti-bending performance. The conductive grid in the conducting layer is wrapped by the semi-solid transparent photosensitive resin matrix, such the conducting layer can better be prevented from scratches and is not easily damaged. The opportunities of contact between the conductive grid and air are greatly reduced, and the conducting layer is not easily oxidized. Therefore, the transparent conductor has quite good conducting performance.
