Copper nanowires (CuNWs) for different synthesis temperatures were prepared by solution-grown method. The surface morphology and electrical resistance of CuNWs were investigated. The surface morphology analysis describes the synthesis of long (＞ 20μm), thin (＜ 60 nm), and mono-dispersed CuNWs. Thus, in the case of temperature treatment from 4 °C to 80 °C in water based solution, the CuNWs has diameter of about 71 nm, length up to 37 μm and electrical resistance (R) at 0.1 Ω. This study suggests that the as-prepared copper nanowires (CuNWs) with diameter and electrical resistance tunability might be utilized as flexible transparent conducting electrode.
