描述了一种通过氧化石墨的热剥离来生产单层官能化石墨烯的方法。该过程产生了由参与氧化和还原过程的反应位点产生的褶皱片状结构。由原子力显微镜测得的单层的拓扑特征与第一性原理原子模型的预测非常吻合。虽然氧化石墨是绝缘体，但通过该方法生产的官能化石墨烯是导电的。
A process is described to produce single sheets of functionalized graphene through thermal exfoliation of graphite oxide. The process yields a wrinkled sheet structure resulting from reaction sites involved in oxidation and reduction processes. The topological features of single sheets, as measured by atomic force microscopy, closely match predictions of first-principles atomistic modeling. Although graphite oxide is an insulator, functionalized graphene produced by this method is electrically conducting.
