Abstract

Cu/TiN hybrid nanofibers were successfully fabricated by applying nitridation procedure to CuO/TiO2 nanofibers. Through modifying the nitridation temperature, the electrical conductivity of Cu/TiN nanofibers was tunable, which could achieve a high value of 320S/cm-approximately three times that of TiN nanofibers. The oxidation resistance property of the resulting Cu/TiN nanofibers was assessed. With the excellent chemical stability of TiN composition, hybrid Cu/TiN nanofibers possessed greatly enhanced thermostability. Moreover, by taking advantage of readily fiber patterning using electrospinning, Cu/TiN nanofiber networks were assembled as transparent electrodes, which reached an optoelectrical achievement of 34.4Ω/sq at 83.2% transparency. Given its low-cost, enhanced thermostability, together with considerable optoelectrical achievement, Cu/TiN nanofiber is therefore expected to offer a new platform for cost-efficient transparent electrode.
