Oxidation can strongly influence the performance of Cu nanowires (CuNWs) by decreasing their conductivity. Here, we identify and investigate a way to prevent the oxidation process of CuNWs to maintain the high conducting performance of CuNWs as transparent electrodes. CuNWs were synthesised using an aqueous method. We prepared several temperature treatments (from 0–300 °C) to represent oxidation of CuNWs in different environments, to study the oxidation process and changes in morphology in detail. Depending on the temperature, smooth and uniform CuNWs exposed to oxidation produced rough Cu2O and CuO nanowires. We then suggest a method of protecting nanowires from oxidation, using the Mayer rod coating method to apply a layer of PEDOT:PSS to a transparent conducting film of CuNWs. The result indicates that this method of protection can protect the film, and maintain a stable, and constant resistance over of time, without effecting the excellent conductivity properties of pure CuNWs.

Cu nanowires (CuNWs) were synthesized in an aqueous solution at low temperature using ethylenediamine (EDA) as a capping agent and hydrazine as a reducing agent. This study investigated the growth of mechanism CuNWs and fabricated the transparent conducting electrode. For the growth mechanism of CuNWs, the study was conducted with an optical microscope, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The performance of the transparent conducting electrode was studied with UV-Vis spectrometer and IV meters. CuNWs growth from Cu nanoparticles (CuNPs) in the solution. Transparent conducting electrode gave a sheet resistance of 48.8 Ohm/sq and the transmittance of 52.63%. The understanding of the growing mechanism of Cu nanowires is important for the development of CuNWs for alternative application as a transparent conducting electrode.

“…The transparent conductor is an essential component in fabricating touchscreens, transparent electrodes, organic solar cells, and organic light-emitting diodes (OLEDs) [1][2][3][4][5][6][7][8]. Currently, Indium Tin Oxide (ITO) is most widely used as a transparent conductor due to its low resistance, about 150 Ωsq −1 , and high transmittance, about 90%.…”

We have successfully demonstrated the synthesis of Cu nanowires (CuNWs) by aqueous solution at low temperatures. We have also studied the fabrication of a transparent conductor using Mayer rod coating. In the present study, the problem with the fabrication of CuNW transparent conductor is low oxidation resistance. Based on this purpose, we developed a facile method for coating poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) on CuNW transparent conductor. The PEDOT:PSS can protect CuNW transparent conductors from oxidation. The morphology and crystal structure of the CuNWs transparent conductor were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). The SEM images show an increase in connectivity of CuNWs after PEDOT:PSS coating and X-ray diffraction shows peaks at 42.52°, 49.68°, 60.94° and 73.43°. The performance of the transparent conductor was investigated by IV-meter analysis and spectroscopy (UV-Vis). The results indicated that the coated transparent conductor with PEDOT:PSS/CuNWs has a much better performance compared to the uncoated one. The CuNW-coated transparent conductor has a resistance of 220 ohm sq-1, while the uncoated one is 1200 ohm sq-1. The newly designed transparent conductor with PEDOT: PSS/CuNWs could serve as new materials for a wide range of high-performance transparent conductors for future practice.
