▎ 摘　　要

A context for the burgeoning emergence of colloidal graphene in various states of oxidation is provided for a collection of detailed reviews and perspectives on the exfoliation, synthesis, and use of colloidal graphene as a functional material in diverse advanced materials. Methods of generation cover orders of magnitude in scale, from bench top to manufacturing, and special attention is given to overlap with extant dispersion technology. Syntheses range from redox manipulations of coal extracts and graphite to multistep synthesis of polycyclic aromatic hydrocarbons. The advanced materials discussed include diverse sensing materials, including an introduction to optoelectronic devices, and numerous energy materials. Challenges for refining our understanding of basic properties of graphene on various length scales are presented. (C) 2015 Elsevier Ltd. All rights reserved.
