Summary: Inspired by the heterophase structure of nacre, a centimetre-sized bulk material consisting of graphene oxide (GO) and amorphous/crystalline MnO2 nanosheets adhered together with polymer-based crosslinkers was prepared, exhibiting high flexural strength and fracture toughness. Experimental and numerical analyses revealed that the ordered heterophase structure and synergistic crosslinking interactions across multiscale interfaces contribute to the superior mechanical properties of the material.

Summary: Inspired by the hierarchical structure of the nacre shell, B4C and graphene nanoplatelets hybrid reinforced laminated Al matrix composites were prepared via flake powder metallurgy. The laminated composites exhibit high relative density, strength, and plasticity, with tensile elongation above 9.97%. The size of Al flakes obtained by ball milling is crucial for the laminated structure, and the combination of hard reinforcement and soft phase Al matrix achieves a good balance of strength and plasticity.

Summary: Researchers have found that the shells of Giant clams have highly ordered cross-lamellar structures made of aragonite nanofibers. This study investigates the microstructures and mechanical properties of different parts of another kind of Giant clams, Tridacna crocea. The results show that the shells of T. crocea also have cross-lamellar structures, but the building units are nanoribbons instead of nanofibers, and the angles between the nanoribbons have a novel structural feature. The mechanical properties of the different parts of T. crocea vary and are strongly related to the multilevel ordered assembly modes of micro-and nanostructures.

Summary: This study investigated the thermal properties and interfacial characteristics of thermoplastic polyurethane (TPU) nanocomposites filled with single-walled carbon nanotubes (SWNTs) using molecular dynamics simulations. The introduction of SWNTs was found to suppress TPU chain dynamics and enhance the hydrogen bond formation between TPU chains and SWNTs. Functionalized SWNTs with polar groups showed improved affinity for TPU molecules, leading to reduced polymer mobility and increased glass transition temperature (T-g). The presence of amine groups had the highest potential for hydrogen bonding with TPU chains, resulting in the lowest polymer mobility and the highest T-g. This research provides insights and guidance for the design of polymer nanocomposites and future simulations involving TPUs.

Summary: A novel waterborne strategy is introduced to fabricate low-cost nanocomposite films with room-temperature phosphorescence (RTP), allowing programmable retention times of RTP signals by adjusting the polymer/nanoclay ratio for information storage and anti-counterfeiting materials. The combination of bioinspired nanocomposite design with RTP materials overcomes limitations in organic RTP compound molecular design and adds programmable temporal features to RTP materials, paving the way for practical applications as novel anti-counterfeiting materials.

Summary: High mechanical performance spun bionanocomposite fibers of chitosan (CHI) filled with cellulose nanofibers (CNFs) were achieved through gel spinning, leading to improved crystallinity and mechanical properties. Increasing the CNF content up to 0.4 wt% in the CHI solution significantly enhanced Young's modulus and tensile strength of the fibers, while further increases in CNF content slightly impacted mechanical parameters due to potential disruption of the CHI matrix hydrogel network. Overall, the addition of 0.4 wt% CNFs into 4 wt% CHI formulations showed optimal compatibility and interface, resulting in bionanocomposite fibers with outstanding mechanical properties.
