TL;DR: The dispersibility of graphene is measured in 40 solvents, with 28 of them previously unreported, and transmission electron microscopy analysis is used to show that the graphene is well exfoliated in all cases.

Abstract: We have measured the dispersibility of graphene in 40 solvents, with 28 of them previously unreported. We have shown that good solvents for graphene are characterized by a Hildebrand solubility parameter of δT ∼ 23 MPa1/2 and Hansen solubility parameters of δD ∼ 18 MPa1/2, δP ∼ 9.3 MPa1/2, and δH ∼ 7.7 MPa1/2. The dispersibility is smaller for solvents with Hansen parameters further from these values. We have used transmission electron microscopy (TEM) analysis to show that the graphene is well exfoliated in all cases. Even in relatively poor solvents, >63% of observed flakes have <5 layers.

Dispersant-assisted liquid-phase exfoliation of 2D materials beyond graphene
TL;DR: Dispersant-assisted liquid-phase exfoliation (LPE) as mentioned in this paper has been extensively used for the LPE of graphene and has been discussed in many reviews, whilst little attention has been given to dispersant assisted LPE for other 2D materials beyond graphene, such as transition metal dichalcogenides (TMDs), hexagonal boron nitride (h-BN) and hexagonal hexagonal nanosheets.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.

TL;DR: In this paper, a colloidal suspension of exfoliated graphene oxide sheets in water with hydrazine hydrate results in their aggregation and subsequent formation of a high surface area carbon material which consists of thin graphene-based sheets.
