Surfactant mediated liquid phase exfoliation of graphene
Commercialization of graphene based applications inevitably requires cost effective mass production. From the early days of research on graphene, direct liquid phase exfoliation (LPE) of graphite has been considered as the most promising strategy to produce high-quality mono or few-layer graphene sheets in solvent dispersion forms. Substantial success has been achieved thus far in the LPE of gr...
متن کاملLiquid-phase Exfoliation of Graphite to Produce High-quality Graphene
Graphene has attracted intense interest due to its exceptional physical and chemical properties as well as its wide potential applications. For applications of two-dimensional graphene, commercially viable sources are necessary. Liquid-phase exfoliation graphite is one of the most promising economical mothed for the mass production of graphene. A number of methods have been developed to achieve...

متن کاملFew‐Layer Antimonene by Liquid‐Phase Exfoliation
We report on a fast and simple method to produce highly stable isopropanol/water (4:1) suspensions of few-layer antimonene by liquid-phase exfoliation of antimony crystals in a process that is assisted by sonication but does not require the addition of any surfactant. This straightforward method generates dispersions of few-layer antimonene suitable for on-surface isolation. Analysis by atomic ...
متن کاملGraphene-Graphene Interactions: Friction, Superlubricity, and Exfoliation.
Graphite's lubricating properties due to the "weak" interactions between individual layers have long been known. However, these interactions are not weak enough to allow graphite to readily exfoliate into graphene on a large scale. Separating graphite layers down to a single sheet is an intense area of research as scientists attempt to utilize graphene's superlative properties. The exfoliation ...
