Composition of Copper Nanowires and Preparation of Transparent Conductive Film by Intense Pulse Light Sintering

Abstract

Copper nanowires （ CuNWs ） with low manufacture price and high electrical conductivity have been successfully synthesized by a simple hydrothermal process. The molecular weight of amine, which was used as surfactant, largely influenced the morphology of synthesis Cu products. As ︲ synthesized CuNWs were coated onto substrate and treated by intense pulse light （ IPL ） technique in ambient atmosphere. The instantaneous deoxidization and decomposition organics on the surface of the CuNWs contributed to the formation of transparent conductive film. A film with low sheet resistance of 13 . 4 Ω / □ and high transmittance of 79 ％ was obtained. Furthermore, stretchable conductor was also realized by coating the CuNWs onto flexible substrate and following IPL sintering treatment. ［ doi:10 . 2320 / jinstmet.J2017013 ］ （ Received Accepted 9, 2017; Published June 23, 2017 ）
