MXenes (Ti3C2TX) are two-dimensional transition-metal carbides with high conductivity and optical transparency. However, transparent MXene electrodes with high environmental stability suitable for various flexible organic electronic devices have rarely been demonstrated. By laminating a thin polymer film onto MXene layer to protect the MXene film from harsh environmental conditions, we present transparent and flexible MXene electronic devices. A thin polymer layer spin-coated onto a transparent MXene electrode provides environmental stability even under air exposure longer than 7 d at high temperatures and humidity levels without degrading the transparency. The resulting polymer-laminated MXene electrode facilitates the development of a variety of field-driven photoelectronic devices, such as light-emitting devices. Furthermore, our PL-MXene electrode exhibits high versatility through successful implementation in pressure sensors and TENGs with excellent operation reliability. |
