Abstract
A method of modifying a coating material includes applying a fluid including a population of particles to a wet coating material disposed on a substrate. The method also includes drying the wet coating material so as to give rise to a coated article, where the particles are at least partially embedded in a surface of the dried coating material. The particles can be metallic nanowires, and a loading of the metallic nanowires in the dried coating material can be above an electric percolation threshold.
Claims35
A method of producing a coated article, comprising:
- applying a fluid and a population of metallic nanowires to a wet coating material disposed on a transparent polymeric substrate, wherein:
- the transparent polymeric substrate comprises a thermoset polymer, and
- the wet coating material comprises a thermoplastic polymer selected from the group consisting of polycarbonate and polyacrylate;
- removing at least a portion of the fluid after the metallic nanowires are applied to the wet coating material and before the wet coating material is dried, wherein the removing at least a portion of the fluid is under a condition of applying an electric field to maintain one or more positions of the metallic nanowires within the wet coating material;
- and
- drying the wet coating material so as to give rise to a coated article, wherein:
- the metallic nanowires are at least partially embedded in a surface of the dried coating material,
- a loading of the metallic nanowires in the dried coating material is above an electric percolation threshold,
- neighboring ones of the metallic nanowires are in electronic contact with one another, and
- the coated article is a transparent conducting electrode.
