MXenes, 2D transition metal carbides, nitrides, or carbonitrides, have been attracted in many electronic and optoelectronic applications, due to their high electronic conductivity (~5000 S/cm), hydrophilicity, and solution processability. However, they suffer from poor stability against oxidative degradation and poor dispersion stability in organic environments. This presentation demonstrates a simple and scalable way to prepare Ti3C2Tx MXene dispersions in non-polar organic solvents. The MXene organic dispersions also exhibit strong oxidation resistance and stable long-term storage. Additionally, the stable MXene dispersions provide an opportunity to prepare printable flexible MXene films or electrodes for various flexible electronic applications including EMI shielding, flexible joule heater and LED display. |
