Effect of Synthesis Temperature on the Morphology and Electrical Properties of Solution-Grown Copper Nanowires (CuNWs)

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 (> 20 mu m), thin (<60 nm), and mono-dispersed CuNWs. Thus, in the case of temperature treatment from 4 degrees C to 80 degrees C in water based solution, the CuNWs has diameter of about 71 nm, length up to 37 mu m and electrical resistance (R) at 0.1 Omega. This study suggests that the as-prepared copper nanowires (CuNWs) with diameter and electrical resistance tunability might be utilized as flexible transparent conducting electrode.
