“…In contrast, the weight loss of DGO was ~23 wt%. This phenomenon might result from the partial reduction of GO by PDA [ 40 , 41 ], which lowers the content of oxygen-containing groups on GO and improves the thermal stability of the nanosheets. The reduction of GO by PDA would also reduce the interlayer spacing, which is confirmed by XRD.…”

Phosphotungstic acid (HPW)-filled composite proton exchange membranes possess high proton conductivity under low relative humidity (RH). However, the leaching of HPW limits their wide application. Herein, we propose a novel approach for anchoring water soluble phosphotungstic acid (HPW) by polydopamine (PDA) coated graphene oxide and halloysite nanotubes (DGO and DHNTs) in order to construct hybrid three-dimensional proton transport networks in a sulfonated poly(ether ether ketone) (SPEEK) membrane. The introduction of PDA on the surfaces of the hybrid fillers could provide hydroxyl groups and secondary amine groups to anchor HPW, resulting in the uniform dispersion of HPW in the SPEEK matrix. The SPEEK/DGO/DHNTs/HPW (90/5/5/60) composite membrane exhibited higher water uptake and much better conductivity than the SPEEK membrane at low relative humidity. The best conductivity reached wass 0.062 S cm−1 for the composite membrane, which is quite stable during the water immersion test.

“…The overall toughness and fracture resistance of natural nacre are also improved by the presence of water-insoluble chitin nanofibrils in the interlamellar membrane that undergo ductile deformation. [117] Hence the addition of cellulose nanofibers to a graphene nanosheet [118] or GO [119] nacre-like composite can significantly improve the tensile strength. Even better, connecting the nanofibers in a 3D network (Figure 6a) rather than in a random alignment more closely mimics the natural nacre structure and leads to unprecedented toughness and fold endurance as well as good thermal stability.…”

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.

“…In this respect, complex biological architectures, displaying self-assembly processes and implying the key role of nanostructuration and nano-objects intrigue researchers and inspire them for the development of innovative engineering materials [ 2 , 3 , 4 , 5 , 6 , 7 ]. Elaboration of bio-inspired materials has already been investigated in a plethora of engineering materials, mimicking natural systems such as nacre, tooth, bone, or wood [ 8 , 9 , 10 , 11 , 12 ]. Practically, it seems that these architectures modify stress transfer mechanisms within the material and boost their strength and fracture toughness thanks to nanostructuration and the development of a “hierarchical architecture” [ 13 , 14 , 15 , 16 , 17 ].…”

Several naturally occurring biological systems, such as bones, nacre or wood, display hierarchical architectures with a central role of the nanostructuration that allows reaching amazing properties such as high strength and toughness. Developing such architectures in man-made materials is highly challenging, and recent research relies on this concept of hierarchical structures to design high-performance composite materials. This review deals more specifically with the development of hierarchical fibres by the deposition of nano-objects at their surface to tailor the fibre/matrix interphase in (bio)composites. Fully synthetic hierarchical fibre reinforced composites are described, and the potential of hierarchical fibres is discussed for the development of sustainable biocomposite materials with enhanced structural performance. Based on various surface, microstructural and mechanical characterizations, this review highlights that nano-objects coated on natural fibres (carbon nanotubes, ZnO nanowires, nanocelluloses) can improve the load transfer and interfacial adhesion between the matrix and the fibres, and the resulting mechanical performances of biocomposites. Indeed, the surface topography of the fibres is modified with higher roughness and specific surface area, implying increased mechanical interlocking with the matrix. As a result, the interfacial shear strength (IFSS) between fibres and polymer matrices is enhanced, and failure mechanisms can be modified with a crack propagation occurring through a zig-zag path along interphases.
