Reverse-Patterning Process of Ti3C2Tx MXene using an Inkjet Printing Technique

This study investigated the transformation of conductive MXene films into non-conductive materials using hydrogen peroxide inkjet printing and introduced a novel reverse-patterning technique. Non-conductive patterns can be formed by multiple printing processes of H2O2 ink on MXene films to transform Ti3C2Tx into TiOx. X-ray photoelectron spectroscopy analysis confirmed the compositional changes of the MXene films, supporting the fabrication of flexible electronics and custom patterns using the proposed technique. The developed method enhances MXene film integration and can be used to create intricate designs, thereby offering significant potential for use in electronic device manufacturing and materials science.
