Abstract

Transition metal dichalcogenides (TMDs) are promising 2D materials which are attracting significant interest because of their distinctive physicochemical properties. The possibility of being exfoliated and dispersed in liquid solutions offers a viable pathway to scalable production. This personal account focuses on recent advancements in 2D TMD inks produced by liquid-phase exfoliation (LPE) methods and intercalation-based electrochemical exfoliation. In particular, different LPE production strategies, like ultrasonication LPE, high-shear mixing exfoliation, and microfluidization, are introduced alongside a broad range of liquid media employed to provide functionalized TMD inks. The main advantage of TMD inks is its scalability, for practical applications in printed optoelectronics, energy storage, and conversion. Furthermore, the chemical functionalization of TMD inks can solve the poor electrical conductivity attributed to edge defects inherent in TMD inks. Finally, the ultimate orientations for future applications of chemically functionalized TMD devices are forecasted, with a specific focus on wearable and flexible printed electronics.

通过液相剥离实现功能化二维过渡金属二钙化油墨的实际应用
过渡金属二钙化物(TMDs)是一种前景广阔的二维材料,因其独特的物理化学特性而备受关注。在液体溶液中剥离和分散的可能性为实现规模化生产提供了一条可行的途径。本报告重点介绍通过液相剥离(LPE)方法和基于插层的电化学剥离法生产二维 TMD 墨水的最新进展。特别是介绍了不同的液相剥离生产策略,如超声液相剥离、高剪切混合剥离和微流体化,以及用于提供功能化 TMD 油墨的各种液体介质。TMD 油墨的主要优势在于其可扩展性,可实际应用于印刷光电子学、能量存储和转换。此外,TMD 油墨的化学功能化可以解决 TMD 油墨固有的边缘缺陷导致的导电性差的问题。最后,预测了化学功能化 TMD 器件未来应用的最终方向,并特别关注可穿戴和柔性印刷电子产品。
