MXenes, like Ti3C2Tx, exhibit significant potential in various applications due to tunable electrical conductivity, mechanical strength, and chemical stability. To optimize synthesis for large-scale production, shorter fabrication times and high single-flake yields with high quality are crucial. This study examines the effects of etching and delamination conditions, including temperature, duration, and processing steps, using hydrochloric and hydrofluoric acids etchants on Ti3C2Tx yield and properties. Our goal is to reduce etching durations from 24 hours to 12, 6, 3, and 1 hour. We also investigate the influence of multilayered Ti3C2Tx clay mixing during the delamination steps with lithium chloride. This presentation highlights the most optimized to-date etching and delamination conditions for achieving a higher Ti3C2Tx production yield while preserving excellent 2D flake quality, including high electrical conductivity at > 18,000 S/cm. Our findings offer valuable insights for optimizing Ti3C2Tx single-flake synthesis, paving the way for efficient large-scale manufacturing. |
