摘要:

石墨烯纖維是2011年才發展起來的一種以天然石墨為最初原料的新型碳質纖維，由石墨烯或者功能化石墨烯納米片的液晶原液經濕法紡絲一維有序組裝而成。石墨烯纖維具有良好的機械性能、電學性能和導熱性能，可用于導電織物、散熱、儲能等領域。將其他物質引入石墨烯纖維中還可得到特定功能的石墨烯復合纖維，如將聚合物加入石墨烯纖維得到結構精巧、力學性能良好的石墨烯仿貝殼纖維；將磁性納米粒子加入即得磁性的石墨烯復合纖維，加入Ag納米線得到高導電的石墨烯復合纖維。石墨烯纖維良好的柔韌性為其在柔性器件如柔性的超級電容器等領域提供了應用。本文綜述了石墨烯纖維的研究現狀，對純石墨烯纖維、石墨烯復合纖維的制備和應用進行了詳細的闡述，并對石墨烯纖維的后續發展方向進行了展望。

Abstract:

Graphene fibers, originally made from natural graphite, represent a new kind of carbonaceous fiber firstly reported in 2011. They are one-dimensionally assembled from neat graphenes or functionalized graphenes liquid crystals by wet-spinning. Graphene fibers exhibit good mechanical, electrical, and thermal performance, providing wide applications in fields of conductive fabrics, heat dissipation, and energy storage. By introducing other molecules into graphene fibers, graphene composite fibers with special function can be produced. Nacre mimic graphene composite fibers with layered structure and excellent mechanical properties can be obtained by adding polymer; magnetic or highly conductive graphene fibers can be fabricated by introducing magnetic or conductive nanoparticles. In addition, graphene fibers can be fabricated into flexible devices such as supercapacitors. Here, we reviewed the progress in research of graphene fibers, including the preparation and application of neat graphene fibers and graphene composite fibers. We also gave a perspective on the future of graphene fibers.
