Silver nanowire (AgNW) is a promising candidate of replacing indium tin oxide because of their outstanding electrical, optical properties and flexibility. Previous printing technologies such as inkjet, screen, gravure printing have been used to fabricate AgNW electrodes for various optoelectronic devices. However, achieving fine line width, uniform thickness, sharp line edge and patterning of various shapes is difficult with conventional printing processes. Here, we report a high-resolution and large-area patterning of highly conductive AgNW transparent electrodes (TCEs) by reverse offset printing and intense pulsed light (IPL) irradiation for flexible integrated electronic devices. The reverse offset printed AgNW TCEs exhibit fine line widths (up to 6 μm) and outstanding pattern quality. After IPL irradiation AgNW TCEs show excellent optical, electrical and mechanical properties. Finally, flexible OLEDs and heaters were successfully fabricated with reverse offset printed AgNW TCEs.
