Manufacturing method of Copper Nanowire Transparent Conductive Electrode using Pulsed laser irradiation

摘要

The present invention relates to a method for manufacturing a copper nanowire transparent conductive electrode using pulse laser irradiation, comprising: dispersing Cu NW in PVP-based ink; Coating the substrate with a Meyer rod; Irradiating the coated Cu NW film with a pulsed laser to weld the nanowire junction and partially remove the film former; Including, In the present invention, the conductivity of the electrode is remarkably improved because the wiring is connected through the nanowire at the intersection point by the laser irradiation process, and the nanowire connects all the nanowires to form a solid network, thereby greatly improving the mechanical durability of the nanowire network. The Cu NW can be prevented from being washed with acetic acid, and the thermal effect of laser irradiation has a remarkable effect of burning the film forming agent covering the wire, which increases the removal rate of the film forming agent by acid treatment.
