Metal nanowires such as silver nanowires (AgNWs) and copper nanowires (CuNWs) have received considerable attention as novel materials for flexible and stretchable transparent electrodes (TCEs). However, it is still difficult to utilize metal nanowires as electrodes for integrated electronic devices due to the lack of a suitable micropatterning process. Recently, various printing technologies such as inkjet, screen, flexographic, and gravure printings have received considerable attention as promising patterning techniques. However, they have critical limitations in achieving micrometer-scale fine line width, sharp line edge and uniform thickness. Therefore, new printing technology should be developed to achieve high-quality and high-resolution micropatterning of metal nanowire based TCEs. Here, I will present a high-resolution and large-area patterning of metal nanowire based TCEs using reverse offset printing and photonic sintering for flexible and stretchable electronic devices.
