One-dimensional metallic nanostructures such as rods, wires, belts, and tubes have drawn considerable attention due to their unique electrical, optical, magnetic, and thermal properties, as well as their promising applications in microelectronics devices. Among them, in particular, silver nanowires (Ag NWs) have gained a significant amount of research highlight because of their high electrical and thermal conductivities. We fabricated transparent conductive films (TCFs) by using Ag NWs and applied them to surface heaters. Ag NWs were dispersed in DI water with carboxymethyl cellulose (CMC) or other organic surfactants. The aqueous suspension of Ag NWs was spin-coated on glass substrates, followed by washing with DI water to remove CMC or other organic surfactants. Heat treatment was performed to eliminate further the CMC or other organic layer wrapping the surface of Ag NWs. The optical transmittances, sheet resistances, and heating ability of the TCFs of Ag NWs were evaluated by using UV-Vis spectroscopy, four-point probe, and thermal imaging camera, respectively. This study will discuss the synthesis of Ag NWs and their TCF properties in detail. |
