The article reviews the liquid exfoliation of layered materials, a versatile method for producing atomically thin, 2-dimensional nanosheets from various materials such as graphene, MoS₂, and MnO₂. These nanosheets exhibit unique properties that differ significantly from their bulk counterparts, making them valuable for a wide range of applications. The review highlights the historical context of exfoliation, from Thomas H. Webb's discovery of vermiculite to Geim and Novoselov's use of Scotch tape to exfoliate graphite into graphene. It discusses the advantages of exfoliation, including increased surface area and the creation of new electronic band structures. The article then focuses on liquid exfoliation techniques, including oxidation, intercalation, ion exchange, and ultrasonication, each with its own benefits and limitations. Recent advancements in liquid exfoliation, such as the production of high-quality graphene nanosheets and the development of composite materials, are also covered. The review concludes by discussing the potential future applications of liquid-exfoliated nanosheets in electronics, energy storage, catalysis, and other fields, emphasizing the need for further research to scale up production and explore a broader range of materials.The article reviews the liquid exfoliation of layered materials, a versatile method for producing atomically thin, 2-dimensional nanosheets from various materials such as graphene, MoS₂, and MnO₂.
