“…To balance the strong covalent bonding, the non-covalent (e.g., -interactions and ionic bonding) is crucial to dissipate the energy allowing plastic deformation. Graphene fibres usually have higher toughness than graphene films due to the reorientation of graphene during tensile testing absorbing deformation energy 272 . Bending and wrinkling of graphene may occur during the spinning process thus strong interaction between graphene and polymer is needed to engineer the defect of graphene 273 .…”

The recent development of nanoscale fillers, such as carbon nanotube, graphene, and nanocellulose, allows the functionality of polymer nanocomposites to be controlled and enhanced. However, conventional synthesis methods of polymer nanocomposites cannot maximise the reinforcement of these nanofillers at high filler content. Approaches to the synthesis of high content filler polymer nanocomposites are suggested to facilitate future applications. The fabrication methods address design of the polymer nanocomposite architecture, which encompass one, two, and three dimensional morphology. Factors that hamper the reinforcement of nanostructures, such as alignment, dispersion of filler as well as interfacial bonding between filler and polymer are outlined. Using suitable approaches, maximum potential reinforcement of nanoscale filler can be anticipated without limitations in orientation, dispersion, and the integrity of the filler particle-matrix interface. High filler content polymer composites containing emerging materials such as 2D transition metal carbides, nitrides, and carbonitrides (MXenes) are expected in the future.Graphical abstract: Approaches to the synthesis of high filler content polymer composites

“…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.

It can be difficult to know where to begin when considering the research opportunities of a material with such outstanding potential as graphene. When searching for a “killer application,” the researcher often neglects to query the world around them, forgetting that nature has been evolving for billions of years to elegantly solve every day problems. Bioinspiration is an intelligent strategy to nucleate new ideas and speed up the innovation process by providing ready‐made prototypes. Graphene is uniquely placed to take advantage of this approach thanks to its superlative properties and versatile nature. In this review, the state‐of‐the‐art in the bioinspired design of graphene‐based materials has been analyzed, and three distinct sources of inspiration have been identified: natural functions, such as adhesion and actuation; natural structures, such as layers and pores; and natural processes, such as surface functionalization and biomineralization. Implementing this philosophy into further graphene research will provide new ways to solve problems and suggest novel applications that may not otherwise be considered.
