2D MXene Suspensions and Their Electronic Applications
|
구종민 박사 한국과학기술연구원 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 that developing a ligand chemistry for MXene flakes and preparing MXene dispersions in organic solvents is key to improve oxidation stability and long-term dispersion stability. 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. |
