Electric field driven exfoliation of MoS2

As ultrathin MoS2 nanosheets are an emerging category of two-dimensional (2D) transition metal dichalcogenide nanomaterials and have aroused increasing research enthusiasm due to their peculiar structure and intriguing characters. Electric field driven exfoliation approaches are promising for the green, controllable and large-scale production of 2D MoS2 flakes, thus making the extensive investigation of MoS2 based materials for prospective applications. In this article, on the basis of the difference of exfoliation electrode, we systematically review recent research and application progress of electric field driven exfoliating MoS2 nanosheets. The possible exfoliation mechanisms of different exfoliation methods and their effects on the crystal structure of MoS2 nanosheets are expound. Furthermore, we discussed the potential applications of different exfoliating methods for preparing MoS2 nanosheets. Lastly, the challenges and opportunities for the electric field driven exfoliation of 2D MoS2 and applications are put forward. (C) 2020 Elsevier B.V. All rights reserved.
