[交流] 最新剥离法石墨烯制备综述已有20人参与

最近Chem. Soc. Rev.发表了一篇有关通过剥离法制备石墨烯的综述，共18页，全文引文166篇。小虫第一次发资源，请多多关照~~~

Graphene, the 2D form of carbon based material existing as a single layer of atoms arranged in a
honeycomb lattice, has set the science and technologysectors alight with interest in the last decade in view
of its astounding electrical and thermal properties, combined with its mechanical stiffness, strength and
elasticity. Two distinct strategies havebeen undertaken for graphene production,i.e. the bottom-up and the
top-down. The former relies on the generation of graphene from suitably designed molecular building
blocks undergoing chemical reaction to form covalently linked 2D networks. The latter occursviaexfoliation
of graphite into graphene. Bottom-up techniques, based on the organic syntheses starting from small
molecular modules, when performed in liquid media, are both size limited, because macromolecules
become more and more insoluble with increasing size, and suffer from the occurrence of side reactions
with increasing molecular weight. Because of these reasons such a synthesis has been performed more and
more on a solid (ideally catalytically active) surface. Substrate-based growth of single layers can be done
also by chemical vapor deposition (CVD) orviareduction of silicon carbide, which unfortunately relies on
the ability to follow a narrow thermodynamic path. Top-down approaches can be accomplished under
different environmental conditions. Alongside the mechanical cleavage based on the scotch tape approach,
liquid-phase exfoliation (LPE) methods are becoming more and more interesting because they are extremely
versatile, potentially up-scalable, and can be used to deposit graphene in a variety of environments and on
different substrates not availableusing mechanical cleavage or growth methods. Interestingly, LPE can be
applied to produce different layered systems exhibiting different compositions such as BN, MoS2,WS2,
NbSe2, and TaS2, thereby enabling the tuning of numerous physico-chemical properties of the material.
Furthermore, LPE can be employed to produce graphene-based composites or films, which are key
components for many applications, such as thin-film transistors, conductive transparent electrodes for
indium tin oxide replacement, e.g.in light-emitting diodes, or photovoltaics. In this review, we highlight the
recent progress that has led to successful production of high quality graphene by means of LPE of graphite.
In particular, we discuss the mechanisms of exfoliation and methods that are employed for graphene
characterization. We then describe a variety of successful liquid-phase exfoliation methods by categorizing
them into two major classes, i.e. surfactant-free and surfactant-assisted LPE. Furthermore, exfoliation in
aqueous and organic solutions is presented and discussed separately.
