Printing holes by a dewetting solution enables formation of a transparent conductive film.

We present hereby a general approach for rapid fabrication of large scale, patterned transparent conductive coatings composed of nanoparticles. The approach is based on direct formation of "2D holes" with controllable diameter onto a thin film composed of metal nanoparticles. The holes are formed by inkjet printing a dewetting aqueous liquid, which pushes away the metal nanoparticles, thus forming a transparent array of interconnected conductive rings.
