Abstract:
1. A composition comprising nano-particles dispersed in a liquid carrier, the composition being in the form of an emulsion, and the 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 solvent, or combination thereof, wherein when the emulsion is coated onto a surface of a substrate and dried to remove the liquid carrier, 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 that are visible under a light microscope, on the surface of the substrate, wherein the coating is transparent to light at wavelengths in the range of 400 to 700 nm.
