Abstract

Aerogels, as extraordinarily lightweight and porous functional nanomaterials, have garnered significant interest in both academia and industry over the past few decades. Graphene-based aerogels, in particular, stand out due to their excellent conductivity properties, high specific surface area, and efficient adsorption efficiency. Despite these advantageous properties, aerogels face challenges in mechanical durability, complicating their processing, especially in applications requiring complex structures. 3D printing technology holds promise for overcoming these limitations through its capabilities in microscale manufacturing, rapid prototyping, and arbitrary shaping. This review summarizes the advantages of graphene-based aerogels and compares various 3D printing techniques used for aerogel fabrication. Furthermore, it also highlights the energy and environmental applications of 3D-printed graphene and graphene-based composite aerogels, including batteries, supercapacitors, electromagnetic shielding, sensors, etc. The review concludes with an exploration of current challenges and provides an outlook on future developments in the 3D printing of graphene-based aerogels.

石墨烯基气凝胶的 3D 打印及其应用

气凝胶作为超轻、多孔的功能性纳米材料，在过去几十年中引起了学术界和工业界的极大兴趣。尤其是石墨烯基气凝胶，因其优异的导电性能、高比表面积和高效的吸附效率而脱颖而出。尽管气凝胶具有这些优势特性，但它在机械耐久性方面面临挑战，使其加工变得复杂，尤其是在需要复杂结构的应用中。三维打印技术具有微尺度制造、快速成型和任意塑形的能力，有望克服这些限制。本综述总结了石墨烯基气凝胶的优势，并比较了用于气凝胶制造的各种三维打印技术。此外，它还重点介绍了三维打印石墨烯和石墨烯基复合气凝胶在能源和环境方面的应用，包括电池、超级电容器、电磁屏蔽、传感器等。综述最后探讨了当前面临的挑战，并展望了石墨烯基气凝胶三维打印技术的未来发展。
