%X 石墨烯气凝胶一般是由石墨烯片层经过湿法化学组装或气相化学生长获得的一种具有连通多孔网络结构的石墨烯三维宏观体材料，表现出极高的比表面积、良好的导电性以及优异的机械性能等，在电化学储能、吸附、催化以及传感等领域有着极为重要的应用。本文从石墨烯气凝胶的结构设计与组装策略出发，综述了近年来石墨烯纳米结构单元在石墨烯气凝胶材料（氧化石墨烯、还原氧化石墨烯、化学气相沉积（CVD）石墨烯、以及复合气凝胶等）中的组装行为，并对石墨烯气凝胶目前的现状及今后发展方向做了简要评述。<br>Graphene aerogels are obtained from graphene sheets through wet chemical assembly or vaporphase chemical growth. They have a three dimensional graphene architecture that has an interconnected network with a high specific surface area, good electric conductivity and other physicochemical properties and thus has important applications in electrochemical energy storage, adsorption, catalysis and sensing. In this review, we will highlight the assembly strategies and structural designs used to introduce the controlled assembly of the graphene sheets in graphene aerogel materials, such as graphene oxide-, reduced graphene oxide-, CVDgrown graphene and composite graphene aerogels. The current challenges and future development of the grapheme aerogels are also discussed
