Nanocomposites, multiphase solid materials with at least one nanoscaled component, have been attracting ever‐increasing attention because of their unique properties. Graphene is an ideal filler for high‐performance multifunctional nanocomposites in light of its superior mechanical, electrical, thermal, and optical properties. However, the 2D nature of graphene usually gives rise to highly anisotropic features, which brings new opportunities to tailor nanocomposites by making full use of its excellent in‐plane properties. Here, recent progress on graphene/polymer nanocomposites is summarized with emphasis on strengthening/toughening, electrical conduction, thermal transportation, and photothermal energy conversion. The influence of the graphene configuration, including layer number, defects, and lateral size, on its intrinsic properties and the properties of graphene/polymer nanocomposites is systematically analyzed. Meanwhile, the role of the interfacial interaction between graphene and polymer in affecting the properties of nanocomposites is also explored. The correlation between the graphene distribution in the matrix and the properties of the nanocomposite is discussed in detail. The key challenges and possible solutions are also addressed. This review may provide a constructive guidance for preparing high‐performance graphene/polymer nanocomposite in the future.

“…[126] In this way, agglomeration of the graphene nanofillers can be avoided, and the toughening mechanism follows that of natural nacre with the efficient stress relaxation coming from crack bridging, branching, and deflection. Using a different type of epoxy can lead to additional shape memory properties [127] or self-monitoring abilities [128] as well as improved toughness. Otherwise, self-monitoring capabilities can be introduced by functionalizing the GO nanosheets to achieve crack-dependent electrical response.…”

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 engineering, the demand for structural materials with properties such as light weight, high strength, high toughness, high dimensional stability, and impact resistance is driving all innovations. 1,2 Take airplane construction as a case: the first airplanes were made of wood, then the phase of aluminum started, followed now by carbon-fiber-reinforced composites for the newest passenger airplanes. Traditional materials, e.g., metals, ceramics, and polymers, have different building blocks, different bonds, and thus different properties.…”
