最近，许多工作集中在通过氧化和超声处理程序的组合剥离石墨烯，然后通过化学方法还原。我们证明，通过使用酚酞作为还原剂和稳定剂，可以容易地还原单个氧化石墨烯片。所得到的非共价官能化的化学还原氧化石墨烯（CRG）可以很好地分散在有机溶剂中，如醇、N，N-二甲基甲酰胺、N，N-二甲基乙酰胺、N-甲基-2-吡咯烷酮等，其可以在大规模生产油分散性石墨烯中给出实际应用，并且在聚合物纳米复合材料制造中具有潜力。
Recently, much work has focused on the exfoliation of graphene through a combination of oxidation and sonication procedures, followed by reduction through chemical methods. We demonstrated that the individual graphene oxide sheets can be readily reduced by using phenolphthalin as both reducing agent and stabilizer. The obtained non-covalently functionalized chemically reduced graphene oxide (CRG) can be dispersed in organic solvents very well, such as alcohol, N,N-dimethylformamide, N,N-Dimethylacetamide, N-methyl-2-pyrrolidone, etc., which can give practical applications in large scale production of oil dispersible graphene and have a potential in polymer nanocomposites fabrication.
