摘要:

石墨烯具有優越的力學、電學、熱學等性能。石墨烯納米片組裝成石墨烯纖維，將石墨烯優異的性能應用到先進的宏觀材料中，石墨烯纖維可用于組裝柔性電極、導電織物等智能器件。不同的制備方法賦予石墨烯纖維不同的功能化性能，比如高溫石墨化處理會大大減少纖維的缺陷，從而獲得很高的力學性能；通過摻雜不同元素，可以使石墨烯纖維具有非常好的導電性和導熱性；通過界面協同作用增強石墨烯片層間的界面強度，使石墨烯纖維在提高力學性能的同時，保證較高的導電性；限域水熱法制備，可以通過控制玻璃毛細管的形狀來獲得不同宏觀形狀的石墨烯纖維。綜述了石墨烯纖維研究的最新進展，主要關注不同的制備方法以及后處理過程對石墨烯纖維的力學性能、電學性能以及功能化應用的影響。

Abstract:

Graphene has superior mechanical, electrical and thermal properties. Graphene fiber (GF) is an ideal bridge for integrating the excellent properties of graphene nanosheets into advanced, macroscopic, and functional materials for applications. Different fabrication techniques endow GF with different functional applications. For example, high temperature graphitization will greatly reduce the defects of fibers in all scales and achieve high mechanical properties. Through doping with different elements, the electrical conductivity and thermal conductivity of graphene fibers are dramatically enhanced. The synergistic interfacial interaction of graphene sheets could endow the graphene fibers with excellent mechanical properties and electrical conductivity at the same time. The GF fabricated through dimensionally confined hydrothermal strategy could be modified to different macroscopic shapes by controlling the shape of the glass capillary. This paper summarizes the significant advances in GFs, including the different preparation and the post�瞭reating processes.
