Coating of ink with Single-walled carbon nanotube (CNT) ink uniformly dispersed allows the manufacture of transparent electrodes that are mandatory in the production of solar array panels, large-size displays, and organic LED lighting devices. The product is used for the manufacture of large-area transparent electrodes at low temperature by coating them with Single-walled carbon nanotube (CNT) ink like indium tin oxide (ITO) without requiring vacuum deposition equipment. Because the ink is transparent and conductive, uncolored heat-generation sheets and sheets colored red and blue can also be manufactured.
