Printed MXenes in Electronics

MXenes, as a class of two-dimensional materials, have emerged as promising candidates for next-generation microelectronics and energy storage devices due to their excellent electrical conductivity, solution processability, structural tunability and outstanding electrochemical performance. In 2019, the Beidaghi group reported the fabrication of all-solid-state micro-supercapacitors (MSCs) via three-dimensional (3D) printing of additive-free and water-based MXene inks.[1] In 2022, the Nicolosi group at Trinity College Dublin demonstrated a 4D printing strategy to fabricate MXene hydrogels with high conductivity and structural tunability, enabling high performance micro-supercapacitors capable of operating at low temperatures.[2] More recently, in 2024, the In group from Korea reported that ligand-functionalised MXenes enable fully printed thin-film transistors with superior environmental stability and performance, advancing MXene-based microelectronics.[3]
