Recently, 3D graphene aerogels (3GAs) with high electrical conductivity, excellent mechanical properties, and fast mass and electron transport have attracted increasing attention and shown wide applications (such as flexible electronics devices, sensors, absorbents, catalysis, energy storage devices, solar steam generation devices, and so on). The drying process becomes an important factor limiting the large-scale preparation of 3GAs. Therefore, how to simplify the preparation process plays an important role in the large-scale application of 3GAs. In this study, we summarize the recent progresses of 3GAs by different drying methods and focus on the effect of robust graphene network on the simple preparation of 3GAs. Besides, the design and synthesis strategies of 3GAs with robust graphene network structures have been systematically discussed. Finally, the emerging challenges and prospective for developing simple preparation and functionalization of 3GAs were outlined. It is expected that our study will lay a foundation for large-scale preparation and application of 3GAs and inspire more new ideas in this field.
近年来，具有高电导率、优异机械性能以及快速质量和电子传输特性的三维石墨烯气凝胶（3GA）受到了越来越多的关注，并展现出广泛的应用（如柔性电子器件、传感器、吸附剂、催化、储能器件、太阳能蒸汽发生装置等）。干燥过程成为限制3GA大规模制备的一个重要因素。因此，如何简化制备工艺对3GA的大规模应用起着重要作用。在本研究中，我们总结了通过不同干燥方法制备3GA的最新进展，并着重探讨了坚固的石墨烯网络对3GA简易制备的影响。此外，还系统地讨论了具有坚固石墨烯网络结构的3GA的设计与合成策略。最后，概述了在开发3GA简易制备和功能化方面出现的挑战和前景。预计我们的研究将为3GA的大规模制备和应用奠定基础，并激发该领域更多新的思路。
