摘　　要：石墨烯基宏观体材料是由石墨烯片层组装构建而成的宏观形态的新型碳质材料,不仅保持了石墨烯片层良好的物理化学性质,同时具有可调控的微纳织构和宏观形态。笔者综述了石墨烯基宏观体的不同宏观形态和构建方法,并着重对自组装方法进行了详细介绍;讨论了石墨烯基宏观体的物化性质,并着重对其在能源储存和转化、催化、生物医学等方面的潜在应用进行了展望;最后对石墨烯基宏观体研究中的挑战以及实际应用前景进行了评述,指出不同维度组装、构建宏观体结构和相关材料是石墨烯走向实际应用的有效手段。The graphene-based macroform （GM） is a new category of macroscopic carbon materials assembled from graphene nanosheets. It possesses superior physical and chemical properties inherited from individual graphene nanosheets, and moreover, has a tunable micro-texture and controlled macro-morphology, which is useful in various areas. In this paper, different macroscopic forms and preparation methods of GM are reviewed, where the self-assembly method is highlighted. The physical and chemical properties of GM are briefly introduced, and the potential applications including energy storage and conversion, catalysis, bio-medi- cine and other aspects are discussed in detail. Finally, the opportunities and challenges of research and applications of GM are com- mented on, and it is concluded that the assembly of graphenes into fibers, films and blocks is an effective strategy towards their practical applications.
