二维石墨烯薄膜的自组装是制备用于实际应用的宏观石墨烯结构的重要策略，例如薄膜和层状纸状材料。然而，具有三维网络结构的石墨烯自组装宏观结构的构建一直没有实现。本文采用一步水热法制备了自组装石墨烯水凝胶(SGH)。SGH具有导电性、机械强度高、热稳定性好、比电容高等特点。具有碳材料固有生物相容性的高性能SGH材料在药物输送、组织支架、仿生纳米复合材料、超级电容器等生物技术和电化学领域具有广泛的应用前景。
Self-assembly of two-dimensional graphene sheets is an important strategy for producing macroscopic graphene architectures for practical applications, such as thin films and layered paperlike materials. However, construction of graphene self-assembled macrostructures with three-dimensional networks has never been realized. In this paper, we prepared a self-assembled graphene hydrogel (SGH) via a convenient one-step hydrothermal method. The SGH is electrically conductive, mechanically strong, and thermally stable and exhibits a high specific capacitance. The high-performance SGH with inherent biocompatibility of carbon materials is attractive in the fields of biotechnology and electrochemistry, such as drug-delivery, tissue scaffolds, bionic nanocomposites, and supercapacitors.
