A Novel Micro-Nano Structure Profile Control Agent: Graphene Oxide Dispersion

Figure 1

Chemical structural models of graphene-based sheets. (a) Graphene consists of a single atomic layer of sp²-hybridized carbon atoms which stack together to form graphite. (b) GO consists of a graphene sheet derivitized by phenyl epoxide and hydroxyl groups on the basal plane and carboxylic acid groups on the edges. The edge-COOH groups can ionize resulting in an electrostatic repulsion between the sheets, allowing single layers to form an aqueous colloidal dispersion [6].
