Abstract
In this study, thin, long, and well-dispersed copper nanowires were obtained via the seed-mediated growth in an organic solvent-based synthesis. The mean length and diameter of nanowire are about 38.7 μm and 49 nm with a high aspect ratio of 790. Large area conducting films was prepared by a fast, low-cost, simple spray deposition of copper nanowires dispersions. These wires were used for nanowire conducting films since their relatively long length is advantage in lowering the sheet resistance. As-synthesized copper nanowires dispersion was sprayed to create highly transparent conductive electrode from 2×2 cm2 to 6×6 cm2, 6.5×10 cm2 even 6×25 cm2. We can use copper nanowires conducting electrode as a touch switch for much equipment such as light LED array, turn on a computer, etc. We also exploit the photothermal effect of copper nanowires, using copper nanowires fabric as a reactor to do some nanomaterials synthesis. Fabric was illuminated by an 808 nm cw laser with different power to control the fabric temperature in order to do different nanomaterials synthesis. Many materials have been successfully synthesized.
