“…Hu et al used sodium alginate (SA) as the guest macromolecule and prepared a GO–SA composite with a strength of 784.9 MPa and a modulus of 58 GPa . Cheng and co‐workers cross‐linked GO sheets with metal ion and 10,12‐pentacosadiyn‐1‐ol, enhancing the strength and toughness of the GFs to 842.6 MPa and 15.8 MJ m −3 , respectively . This family of guest polymers can be extended to a variety of species, such as hyperbranched polyglycerol, glutaraldehyde, polyacrylonitrile, and poly(vinyl alcohol) (PVA), which can reinforce graphene‐based macroscopic materials with different topologies .…”

Graphene fiber (GF) is a macroscopically assembled fibrous material made of individual units of graphene and its derivatives. Beyond traditional carbon fibers, graphene building blocks consisting of regulable sizes and regular orientations of GF are expected to generate extreme mechanical and transport properties, as well as multiple functions in smart electronic fibrous devices and textiles. Here, the features of GF are presented along four lines: preparation, morphology, structure–performance correlations, and state‐of‐the‐art applications as flexible and wearable electronics. The principles, experiments, and keys of fabricating GF from graphite with different methods, focusing on the industrially viable mainstream strategy, wet spinning, are introduced. Then, the fundamental relationship between the mechanical and transport properties and the structure, including both highly condensed structures for high‐performance and hierarchical structures for multiple functions, is presented. The advances of GF based on structure–performance formulas boost its functional applications, especially in electronic devices. Finally, the possible promotion methods and structural–functional integrated applications of GF are discussed.

“…In this way, defects within the GBF were further minimized, leading to a remarkable enhancement in the tensile strength (822%), modulus (490%), and elongation (161%) as compared to the pristine GBF. The method of enhancing the toughness via a bioinspired nacre‐like structure was recently reported by Cheng and co‐workers . The mixture of GO and chitosan was wet spun through a CaCl 2 coagulating bath and subsequently reduced by hydroiodic (HI) acid .…”

investigated [17][18][19][20] for building graphene-based fibers (GBFs) over recent years. [21][22][23] These unique macroscopic 1D assemblies of microscopic 2D graphene building blocks are of lightweight, high specific surface area (SSA), and remarkable mechanical and electrical properties, thus qualifying them as ideal materials for fiber electronics. [14,[24][25][26] Currently, the well-developed wet-spinning method is widely adopted in preparing GBFs, [27,28] while newly designed spinning methods with microfluidic spinnerets and different kinds of coagulation bath have yielded GBFs with novel structures and functions. Apart from these methods, emerging techniques such as chemical vapor deposition (CVD) and twisting have been developed to meet different applications of GBFs in strain sensors, stretchable SC, and multifunctional actuators. [9,29,30] Together with the evolution in their preparation, mechanical and electrical properties of GBFs have been considerably enhanced since their debut. Bioinspired strengthening and toughening strategies for membranes have been found to work for GBFs as well, and atomic doping methods have efficiently increased electrical conductivity of GBFs to a record value of 2.2 × 10 7 S m −1 , [31] which is even comparable to that of certain metals such as nickel (1.5 × 10 7 S m −1 ) and aluminum (3.5 × 10 7 S m −1 ). Based on their novel structures and significantly enhanced mechanical/electrical properties, GBFs have found their substantial uses particularly in newly designed, high-performance electrochemical devices for energy conversion and storage.Several excellent reviews have witnessed the rapid development of GBFs. [17,20,23] For example, Chou and co-workers [18] previously gave a comprehensive review on the synthesis, device performance, and potential applications of GBFs. Another review presented by Gao and his colleagues [32] focused on the microscopic mechanism during liquid crystal formation and summarized its effects on producing continuous fibers. Additionally, applications of GBFs in flexible/ wearable SCs and bioinspired nanocomposites were specifically discussed by Huang et al. [25] and Cheng and co-workers, [33] respectively. In this featured article, we mainly focus on very recent research advances in GBFs over the past few years and introduce progresses in preparation techniques, strategies for performance enhancement and novel applications (Figure 1), aiming to provide a state-of-the-art update for GBFs as well as perspectives for their future development.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 ...

“…Inspired by the biomaterials such as nacres, graphene could be composited with an organic component to obtain high‐performance brick‐mortar nanostructures, in which graphene served as the tough brick and organic component acted as the adhesive (i.e., mortar). Motivated by this strategy, organic components including small molecules and polymers were introduced to fabricate graphene‐based composite fibers enhanced by cation‐coordination . For instance, Cheng and co‐workers used a two‐step method to prepare GO‐Ca 2+ ‐CS composite fibers, in which GO/CS fibers were first synthesized and then immersed in a CaCl 2 solution for coordination (Figure e) .…”

nanobelts), 2D materials exhibit exceptional physical properties including large theoretical surface area, tunable electronic properties, high optical transparency, and excellent mechanical properties. [2] However, the strong re-stacking tendency of 2D materials caused by van der Waals interaction may result in serious loss of surface area, which inevitably weakens their unique properties. Besides, 2D materials always show intrinsic deficiencies for specific applications, despite the merits mentioned above. As a typical example, TMDs possess high theoretical specific capacities for lithium-ion storage but exhibit unsatisfied cyclability and rate capability in practice, because of their aggregation, low conductivity as well as huge volume expansion during lithium-ion insertion/extraction. [3] One effective way to solve these problems is to construct hybrid nanostructures based on 2D materials. [4][5][6][7][8] Hybrid nanostructures, as a class of composite materials, are composed of two or more nanostructured building blocks. [9,10] Hybrid nanostructures not only can energetically combine the intriguing merits and overwhelm the deficiencies of each building block, but also may generate new functions and properties. [3][4][5][6][7][8][11][12][13] These advantages make hybrid nanostructures based on 2D materials highly promising for practical applications with high performance. [14][15][16][17][18] Regarding the multicomponent composition of hybrid nanostructures, the interfacial interaction between the building blocks lays the foundation for structural and morphological stability, thereby influencing the functions and properties of the resulting hybrid nanostructures. [19][20][21][22] In this sense, the rational design and construction of reliable interfacial interaction for hybrid nanostructures are not only important for achieving improved performance, but also critical for understanding the fundamentals of structureproperty relationship.Generally, there are five types of interfacial interactions, i.e., covalent bond, coordination bond, hydrogen bond, π-π interaction, and electrostatic interaction. [19][20][21][22] Covalent bond and coordination bond are much stronger than the other three in terms of bond energy, so the former two are more favorable for constructing hybrid nanostructures with reliable interfacial interaction. [19] However, most 2D materials are chemically inert, which means the covalent modification is not suitable for them. Alternatively, there are coordination atoms in most of 2D materials and their derivatives, and hence coordination 2D materials have received tremendous scientific and engineering interest due to their remarkable properties and broad-ranging applications such as energy storage and conversion, catalysis, biomedicine, electronics, and so forth. To further enhance their performance and endow them with new functions, 2D materials are proposed to hybridize with other nanostructured building blocks, resulting in hybrid nanostructures with various morphologies and structures. The prop...
