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 کاملScalable production of large quantities of defect-free few-layer graphene by shear exfoliation in liquids.
To progress from the laboratory to commercial applications, it will be necessary to develop industrially scalable methods to produce large quantities of defect-free graphene. Here we show that high-shear mixing of graphite in suitable stabilizing liquids results in large-scale exfoliation to give dispersions of graphene nanosheets. X-ray photoelectron spectroscopy and Raman spectroscopy show th...

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 کاملIn silico free energy predictions for ionic liquid-assisted exfoliation of a graphene bilayer into individual graphene nanosheets.
Free energies for graphene exfoliation from bilayer graphene using ionic liquids based on various cations paired with the bis(trifluoromethylsulfonyl)imide anion were determined from adaptive bias force-molecular dynamics (ABF-MD) simulation and fall in excellent qualitative agreement with experiment. This method has notable potential as an a priori screening tool for performance based rank ord...
