Abstract:
1. A method of producing an article comprising: (a) providing a composition comprising nano-particles dispersed in a liquid carrier comprising (a) water, a water-miscible organic solvent, or combination thereof and (b) an organic solvent that evaporates more quickly than the water, water-miscible organic solvent, or combination thereof, wherein the combination of (a) the water, water-miscible organic solvent, or combination thereof and (b) the organic solvent that evaporates more quickly than the water, water-miscible solvent, or combination thereof, together form an emulsion; (b) applying the composition to a surface of a substrate; and (c) drying the composition to remove the liquid carrier, whereupon the nano-particles self-assemble to form a transparent and electrically conductive coating in the form of a network-like pattern that includes interconnected traces defining randomly shaped cells on the surface of the substrate, wherein the coating is transparent to light at wavelengths in the range of 400 to 700 nm.
