Edge-Selectively Functionalized Graphite |
| 초록 |
We demonstrate efficient and eco-friendly methods for the scalable synthesis of low-cost and high-quality graphene. The approach involves edge-selective functionalization of graphite as a precursor for graphene via a “direct” covalent attachment of organic molecular wedges and/or functional groups to the edges of pristine graphite. The approach is the first case of “direct” functionalization of pristine graphite. Unlike graphite/graphene oxide (GO), it is an important step toward high-yield exfoliation of three-dimensional graphite into two-dimensional graphene nanosheets without basal plane distortion. The resultant edge-selectively functionalized graphite is readily dispersible in common organic solvents with high concentration. The improved dispersibility is driven by a strong interaction between the wedges and/or functional groups on graphite edges and the corresponding solvent. |
