Abstract
The fabrication of low cost conductive transparent layers with appropriate flexibility is a major challenge for developing the next generation of optoelectronic devices. Metal oxide nanofibers with aligned and random orientation, as conductive and high transparent layers, were fabricated through electrospinning method followed by the calcination process. The prepared samples were characterized with scanning electron microscopy (SEM), four-point probe device, and diffuse transmittance Spectroscopy (DTS) for evaluating their conductivity and transparency properties. The diameter of the as-spun fibers is in the range of 270 nm- 1 μm and annealed fibers have diameter about 60 nm–300 nm with mesoporous structure. Optimized electrospun CuO nanostructure mats showed high transparency in the range of 70%–90% and the sheet resistance of 0.38 MΩ/sq to 5.41MΩ/sq. The results show the potential of metal oxide nanostructures as transparent conductive layers for applications such as touch screens which need high resistivity and transparency. • Metal oxide nanostructures as transparent conductive layers with high resistivity and transparency were successfully produced. • Optimized electrospun CuO nanostructure mats showed high transparency in the range of 70%–90% and the sheet resistance of 0.38 MΩ/sq to 5.41MΩ/sq. • The transparency of the layers could be adjusted by changing the fibers orientation and thickness in the fibrous structure.
