Transparent conductors, which are widely used for touch panels, liquid crystal displays, light-emitting diodes, solar cells, and electronic papers and so forth. At present, indium tin oxide (ITO) thin film have been commonly used as a standard transparent conductor in various optoelectronic devices, but indium has the disadvantage due to its scarcity and expensiveness.In this study, we demonstrate a facile fabrication method of two-dimensional aluminum nanowire (Al NW) network on a poly(ethylene terephthalate) (PET) film works a transparent conductor with the transmittance (T) of 80% and the sheet resistance (Rs) of 45 O sq-1. The Al NW network was prepared by wet chemical etching of an Al thin layer using electrospun polymer nanofiber as a sacrificial mask template. Al NW is a pragmatic option for transparent conductors because of the characteristics of Al (i.e., good electrical conductivity, stability in ambient condition, and relatively low-cost due to its abundance).
