The rapid rise in the utility and applications of two-dimensional layered materials (2DLMs) necessitates developing means for their scalable mass production. Established synthesis methods such as epitaxial growth, chemical intercalation, and liquid phase shear exfoliation are all limited by long processing times. We show that gaseous-phase exfoliation, which takes advantage of the shear force of high-speed gas flows, is a promising route for fast and continuous production of 2DLMs. The absence of solvents or chemical reactants makes this process environmentally friendly and versatile to be applied to arbitrary 2DLMs. The effects of key process parameters (e.g., shear force/rate, orifice size and shape, gas species) in the gaseous-phase exfoliation process on the resultant 2DLM morphology are investigated. This study establishes a systematic foundation for developing gaseous-phase exfoliation towards a cost-effective manufacturing process while yielding high-quality 2DLMs.
