“…Baeza et al. [ 120 ] also used solvent welding or inter‐microlayer diffusion of polymer molecules for nacre‐like bulk structural composite design. Instead of the partial rehydration or resolvation process of microfilm building blocks, they directly stacked the gelatinized alumina nanosheet‐thermoplastic polyurethane (TPU) microfilm building blocks (semi‐finished products) by way of step‐wise casting to prefabricate nacre‐like bulk structural composites.…”

Biological materials, although composed of meager minerals and biopolymers, often exhibit amazing mechanical properties far beyond their components due to hierarchically ordered structures. Understanding their structure‐properties relationships and replicating them into artificial materials would boost the development of bulk structural nanocomposites. Layered microstructure widely exists in biological materials, serving as the fundamental structure in nanosheet‐based nacres and nanofiber‐based Bouligand tissues, and implying superior mechanical properties. High‐efficient and scalable fabrication of bioinspired bulk structural nanocomposites with precise layered microstructure is therefore important yet remains difficult. Here, we focus on one straightforward bottom‐up film‐to‐bulk assembly strategy for fabricating bioinspired layered bulk structural nanocomposites. The bottom‐up assembly strategy inherently offers a methodology for precise construction of bioinspired layered microstructure in bulk form, availability for fabrication of bioinspired bulk structural nanocomposites with large sizes and complex shapes, possibility for design of multiscale interfaces, feasibility for manipulation of diverse heterogeneities. Not limited to discussing what has been achieved by using the current bottom‐up film‐to‐bulk assembly strategy, we also envision how to promote such an assembly strategy to better benefit the development of bioinspired bulk structural nanocomposites. Compared to other assembly strategies, the highlighted strategy provides great opportunities for creating bioinspired bulk structural nanocomposites on demand.This article is protected by copyright.

The nacre‐inspired multi‐nanolayer structure offers a unique combination of advanced mechanical properties, such as strength and crack tolerance, making them highly versatile for various applications. Nevertheless, a significant challenge lies in the current fabrication methods, which is difficult to create a scalable manufacturing process with precise control of hierarchical structure. In this work, a novel strategy is presented to regulate nacre‐like multi‐nanolayer films with the balance mechanical properties of stiffness and toughness. By utilizing a co‐continuous phase structure and an extensional stress field, the hierarchical nanolayers is successfully constructed with tunable sizes using a scalable processing technique. This strategic modification allows the robust phase to function as nacre‐like platelets, while the soft phase acts as a ductile connection layer, resulting in exceptional comprehensive properties. The nanolayer‐structured films demonstrate excellent isotropic properties, including a tensile strength of 113.5 MPa in the machine direction and 106.3 MPa in a transverse direction. More interestingly, these films unprecedentedly exhibit a remarkable puncture resistance at the same time, up to 324.8 N mm−1, surpassing the performance of other biodegradable films. The scalable fabrication strategy holds significant promise in designing advanced bioinspired materials for diverse applications.
