Graphene fiber: a new trend in carbon fibers

Abstract

New fibers with increased strength and rich functionalities have been untiringly pursued by materials researchers. In recent years, graphene fiber has arisen as a new carbonaceous fiber with high expectations in terms of mechanical and functional performance. In this review, we elucidated the concept of sprouted graphene fibers, including strategies for their fabrication and their basic structural attributes. We examine the rapid advances in the promotion of mechanical/functional properties of graphene fibers, and summarize their versatile applications as multifunctional textiles. Finally, a tentative prospect is presented. We hope this review will lead to further work on this new fiber species.

2D Material Liquid Crystals for Optoelectronics and Photonics

“…83 Fu et al demonstrate the use of graphene oxide liquid crystals can be applied as composite inks for the formation of electrodes in 3D printing applications 84 due to the intrinsic self-assembly that means they retain ordering of the GO platelets on drying of the solvent. The development of fibers formed from graphene, GO or reduced GO is a widely reviewed maturing area for investigation, [85][86][87][88] with many proposed applications such as in conducting wires, energy storage and conversion devices, actuators, field emitters, catalysis and optoelectronic and photonic devices. One of the most promising developments in this field, and of particular interest here, has been the use of the liquid crystal phase to improve the homogeneity and ordering of the fibers produced; numerous examples exist where fibers comprised of 2D materials have also been produced by the wet-spinning of liquid crystalline solutions.…”

Recent Advances in Effective Reduction of Graphene Oxide for Highly Improved Performance Toward Electrochemical Energy Storage

“…[2][3][4][5][6] Graphene exhibits outstanding properties such as ultralarge specific surface area, great flexibility, high chemical stability, and superior electric and thermal conductivity. [7][8][9][10][11][12] Such amazing properties suggest that use of graphene could deliver excellent performances for a wide range of functional applications such as photovoltaic cells, sensors, chemical energy storage devices, transistors, and transparent electrodes. [13][14][15][16][17][18] In particular, in the field of chemical energy storage, graphene is considered as a next-generation material with great potential to improve the energy density and power density, leading to extensive efforts being directed toward exploiting graphene-based materials in advanced energy storage devices.…”

New Perspectives on Graphene/Polymer Fibers and Fabrics for Smart Textiles: The Relevance of the Polymer/Graphene Interphase

“…The introduction of graphene-based smart materials in the market will depend fundamentally on the methodologies developed to incorporate graphene into textile devices. In this respect, there has been much research directed toward the fabrication of graphene fibers (GrFs) (Meng et al, 2015;Xu and Gao, 2015), which exhibit very high-electrical conductivities, but have the drawback of poor and unreliable mechanical performance. Thus, combination of graphene with the polymer fibers is an alternative approach to enhance mechanical strength, toughness and flexibility during use, and deformation.…”
