“…Besides the above-listed examples, there are too many excellent reports that appeared recently on the sustainable application of bioinspired mechanically robust mechanical properties, as a few summarized in Figure 16. [145][146][147][148][149][150][151] These examples demonstrate how bioinspiration can expand our knowledge in designing advanced functional materials for applications in sustainable energy and environmental technologies by learning from the unique wettability, transport, and transpiration features of the natural structures, while employing their excellent mechanical performance or unique mechanical phenomena proactively or passively. Even though the raw materials are still the conventionally available common materials, the fabricated bioinspired materials exhibit much improved structural or functional properties through the manipulation of surface, interface, or channel structures or the modification via proper functional groups, and thus deliver significantly enhanced performances of the sustainable energy or environmental devices.…”

“…Dragonfly has a superior flight ability, which is related to its strong and tough wings. [ 27,28 ] The toughness of the wings is inseparable from its specific fractal structure. The dislocation nodes in the wings can effectively disperse stress and avoid damage.…”

The simultaneous enhancement in strength and toughness seems to be an intrinsic contradiction in multiple material designs, including the structural regulation of polymer composites. In this study, benzimidazole-containing aromatic-polyamide thin films are used as typical rigid polymers with high strength and modulus to study their strength-toughness collaboration via a multi-scaled stress distribution mechanism. A fully organic deformable filler with a fractal structure is designed. Utilizing the large-scale deformability of the filler to absorb the energy and dislocation node structure of the filler to disperse the stress, the composite thin film is significantly toughened, which is reflected in the elongation at break increased by 144.9% and energy at break increased by 154.2%. In addition, the specific fractal structure of the filler provided a larger interaction area, which enhanced the interfacial bonding force and improved the strength of the film. Moreover, owing to the larger interaction area provided by the fractal structure, the interface bonding force between the filler and matrix due to the similar chemical structures is further improved and the tensile strength of the composite thin film is increased from 389.2 ± 11.98 to 426.2 ± 4.41 MPa.

Nature is a substantial repository for various kinds of aquatic, terrestrial, and wind‐borne plants and animals adapting extensively to sustain life on earth's different environmental conditions. The organisms or structures of these natural creatures possess extraordinary properties or functionalities through well‐organizing usually weak biopolymers and bioinorganic structures, which provide good examples to emulate their mechanical and structural characteristics in materials innovations and discoveries. This review collectively investigates the studies of the structures and mechanical properties of some representative fauna and flora with robust mechanical properties and the corresponding bioinspired materials with mimicking structures and mechanical properties. By learning from the natural structures with robust mechanical properties, bioinspired materials and composites with superior mechanical performance to the constituent materials have been designed and fabricated. Via this study, there is hope to draw some principles for designing innovative materials with extraordinary properties from existing common materials by learning from nature. It is expected that the understanding of the extraordinary natural mechanical properties and the robust bioinspired materials can provide some insights into the design of novel materials and composites.
