Facile synthesis of very-long silver nanowires for transparent electrodes

Silver nanowires >60 mu m and even 100 mu m in length have been synthesized using a polyol process by adjusting the stirring speed at 130 degrees C. The length is over three times longer than that of normal AgNWs. These wires have a uniform similar to 60 nm diameter, independent of the stirring speed. At 91% transmittance at 550 nm, AgNW films fabricated at room temperature achieved 25 Omega per square sheet resistance, which is superior to that of expensive ITO films.
