Abstract

We report the microwave synthesis of copper nanowires (CuNWs) by using alkylamine-mediated approach. The aspect ratio of CuNWs of this study was two–fold compared to the previous microwave-assisted synthesis study. In addition, we showed that microwave synthesis could produce high aspect ratio CuNWs in a much shorter time compared to conventional method. Purification process of CuNWs was done via a simple and fast centrifugation method using water-hydrophobic organic solvent system. We also show the importance of purification process on the performance of the fabricated transparent conductive electrode (TCE) films. Purified CuNWs TCE showed a low sheet resistance of 35 Ω/sq with high transparency of 81% (at λ550 nm). Furthermore, we demonstrated how the retreatment of acetic acid was able to assist CuNWs to regain its high conductivity even after five cycles of repetitive continuous oxidation process.
