我们报道了一种在邻二氯苯(ODCB)中制备未官能化和非氧化的石墨烯纳米片均匀分散的简单、高产率的方法。各种石墨材料的超声波/离心法可得到稳定、均匀的分散体。石墨烯的ODCB分散体避免了苛刻的氧化化学，并允许通过一系列方法对石墨烯材料进行化学功能化。此外，由ODCB-石墨烯制备的薄膜具有高导电性。
We report a simple, high-yield method of producing homogeneous dispersions of unfunctionalized and nonoxidized graphene nanosheets in ortho-dichlorobenzene (ODCB). Sonication/centrifugation of various graphite materials results in stable homogeneous dispersions. ODCB dispersions of graphene avert the need for harsh oxidation chemistry and allow for chemical functionalization of graphene materials by a range of methods. Additionally, films produced from ODCB-graphene have high conductivity.
