摘要:: 石墨烯是一种由碳原子以sp2杂化方式结合形成的单原子层厚度的二维纳米碳材料，具有优异的力学、电学、热学、磁学等性能，是当前研究的热点和焦点。石墨烯纤维是石墨烯纳米片层在一维受限空间的组装体，使得石墨烯在纳米尺度的优异性能遗传到宏观尺度，极大地拓展了石墨烯的应用领域。自2011年首次制备获得石墨烯纤维以来，至今为止已经开发了以湿法纺丝为代表的多种制备方法，并且石墨烯纤维已经在能量转换、能量存储、传感响应等领域取得了一系列应用。归纳整理了石墨烯纤维的制备方法和应用，同时总结了石墨烯纤维目前存在的问题以及未来发展的展望。

Abstract:: Graphene is an allotrope of carbon consisting of a single layer of carbon atoms by sp2 bond. With excellent mechanical, electrical, thermal and magnetic properties, graphene is being extensively studied in both academic and industrial fields. Graphene fiber is an assembly of graphene nanosheets in onedimensional confined space, which will possess excellent properties originated from graphene. Since the advent of graphene fiber in 2011, a variety of preparation methods have been developed, especially wet spinning. Graphene fibers have already shown great potential in energy conversion and storage, sensing and other fields. The preparation methods and applications of graphene fiber are summarized in this review. Afterwards, the existing difficulties of graphene fiber and the prospects of future development will be discussed in detail.
