'Liquid exfoliation is a synthesis technique used to break apart layered materials, such as graphite, MoS₂, and various clays, into individual, atomically thin nanosheets. In liquid exfoliation, the bulk layered material is dispersed in a liquid medium, where its weak van der Waals forces holding the layers together can be overcome. This is achieved through several methods: oxidation, which modifies the material chemically; ion intercalation or exchange, where ions are inserted between the layers to increase spacing; and surface passivation by solvents, which helps to weaken the interlayer attractions. The combination of these methods allows the layered crystals to be delaminated into high-aspect ratio nanosheets with a large surface area, making them suitable for creating thin films, composites, and other advanced materials.'
