Graphene-based fibers (GBFs) are macroscopic 1D assemblies formed by using microscopic 2D graphene sheets as building blocks. Their unique structure exhibits the same merits as graphene such as low weight, high specific surface area, excellent mechanical/electrical properties, and ease of functionalization. Furthermore, the fibrous nature of GBFs is intrinsically compatible with existing textile technologies, making them suitable for applications in flexible and wearable electronics. Recently, novel synthetic methods have endowed GBFs with new structures and functions, further improving their mechanical and electrical properties. These improvements have rapidly bridged the gaps between laboratory demonstrations and real-life applications in fiber-shaped batteries, supercapacitors, and electrochemical sensors. Recent advances in the fabrication, optimization, and application of GBFs are systematically reviewed and a perspective on their future development is given.
基于石墨烯的纤维（GBFs）是由微观二维石墨烯片作为构建单元形成的宏观一维组件。它们独特的结构展现出与石墨烯相同的优点，如重量轻、比表面积高、优异的机械/电学性能以及易于功能化。此外，GBFs的纤维特性与现有的纺织技术本质上兼容，使其适用于柔性和可穿戴电子设备。最近，新颖的合成方法赋予了GBFs新的结构和功能，进一步改善了它们的机械和电学性能。这些改进迅速弥合了实验室演示与纤维状电池、超级电容器和电化学传感器实际应用之间的差距。本文系统地综述了GBFs在制备、优化和应用方面的最新进展，并对其未来发展给出了展望。
