Laser Patterning of Ultralong Copper Nanowires Network for Transparent Electrodes

Abstract
Ultralong copper nanowires have shown promise for use in next-generation conducting materials for transparent conductors owing to their low sheet resistance, natural abundance, and high transmittance properties. Additionally, ultralongcopper nanowires can be easily synthesized via low-cost solution-based processes. However, very little work has been done on developing patterning techniques for such copper nanowire-based transparent conductors, although the use of patterned transparent conductor is continuously increasing due to the explosive growth of the touchscreen market. In this study, we introduce a facile method to enhance the functionality of a patterned metallic transparent conductor through selective laser ablation of copper nanowire percolation network. By scanning focused nanosecond pulsed laser on ultrahigh aspect ratio copper nanowire percolation network, nanowires are selectively ablated and patterned without using any conventional chemical etching or photolithography steps.
