Abstract
An article is disclosed comprising a network-like pattern of conductive traces formed of at least partially-joined nanoparticles that define randomly-shaped cells that are generally transparent to light and contain a transparent filler material. In a preferred embodiment, the filler material is conductive such as a metal oxide or a conductive polymer. In another preferred embodiment, the filler material is an adhesive that is can be used to transfer the network from one substrate to another. A preferred method of forming the article is also disclosed wherein an emulsion containing the nanoparticles in the solvent phase and the filler material in the water phase is coated onto a substrate. The emulsion is dried and the nanoparticles self-assemble to form the traces and the filler material is deposited in the cells. An electroluminescent device is also disclosed wherein the article of the invention forms a transparent electrode in the device.
