Recent Progress in Two-Dimensional Material Exfoliation Technology and Enlightenment for Geological Sciences

Mechanical exfoliation technology is vital for the development of two-dimensional (2D) materials. This technology has also facilitated the verification of the performance of electronic and optical devices made from 2D materials. In this Perspective, we provide an overview of exfoliation techniques and highlight key physical properties. Additionally, we explored the chemical instability of certain 2D materials and proposed practical solutions to enhance their stability. Furthermore, we discuss the advantages of suspended 2D materials, which demonstrate improved compatibility and properties compared to nonsuspended materials. A particularly intriguing aspect of this Perspective is the exploration of the similarities between the Earth's crust and 2D materials, offering insights into the formation mechanisms of geological phenomena. In this context, 2D materials may serve as simulators for studying geological processes. We hope that this Perspective stimulates further research into exfoliation technology and the physical/chemical properties of 2D materials while providing new inspiration for earth science investigations.
