In the present work, nacre-like graphene nanoplatelets (GNPs)/epoxy films at different filler content have been prepared by a top-down manufacturing technology and their mechanical properties in tension have been experimentally evaluated. The elastic modulus has been found to exhibit a maximum between...
REPORT◥MATERIALS SCIENCEImpact-resistant nacre-liketransparent materialsZ. Yin, F. Hannard, F. Barthelat*Glass has outstanding optical properties, hardness, and durability, but its applications arelimited by its inherent brittleness and poor impact resistance. Lamination and temperingcan improve impact ...
Here we introduce a gradient structure in commercial pure titanium utilizing the ultrasonic surface rolling process (USRP) technique31,32(Fig.1and Methods). We achieved a gradient structure featuring a surface layer (<200 μm in depth) of nacre-like nanolaminated (or so-called “brick-and-mo...
Nacre, the iridescent material of the shells of pearl oysters and abalone, consists mostly of aragonite (a form of CaCO3), a brittle constituent of relatively low strength (≈10 MPa). Yet it has astonishing mean tensile strength (≈150 MPa) and fracture energy (≈350 to 1,240 J/m2). ...
Thanks to meticulous selection of components, and ingenious design of the bio-inspired nacre-like structure, the B-GO/wSBRc will possess out-standing reusable anti-corrosion performance. In addition, the anti-corrosion mechanism was revealed in experimental and theoretical dimensions. The B-GO/wS...
Nacre is generally regarded as tough body armor, but it was often smashed by predators with a certain striking speed. Nacre-like architectures have been demonstrated to dissipate abundant energy by tablets sliding at static or specific low-speed loads, b
Effectively suppressing vanadium permeation in vanadium redox flow battery application with modified Nafion membrane with nacre-like nanoarchitectures A novel self-assembled composite membrane, Nafion-[PDDA/ZrP]with nacre-like nanostructures was successfully fabricated by a layer-by-layer (LbL) method and....
Taking a leaf out of Nature's book, the use of nacre-like structure in the materials synthesis has generated notable successes in creating novel structural composites but has yielded few practical advances in metals. Here we have successfully architected the intricate hierarchical microstructure, the ...
In summary, we have shown the nacre-like mechanically robust heterojunction fabricated by functionalized and heterogeneous nanosheets. The IGM shows higher toughness, up to 9.84 MJ m−3, than that of other reported materials and natural nacre structure. The IGM is able to efficiently control the...
The nacre-like structures widely exist in biomaterials and bioinspired composites, where the tension-shear load transfer is the common load carrying mode due to the discontinuous platelet. However, under bending deformation the local tension-shear load transfer is coupled with the global bending deforma...
