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 ...
Inspired by the layered structure and extraordinary strength and toughness of natural nacre, nacre-like nanolignocellulose/poly (vinyl alcohol)/TiO2composites possessed the similar layered structure of natural nacre were constructed through hot-pressing process. Poly (vinyl alcohol) and TiO2nanoparticles ...
Firstly, we use a GF skin to trigger unstable failure in nacre-like mesolayers, and show how the damage mode in the latter changes from pull-out to brittle fibre fracture due to the interaction with the GF skin. Secondly, we demonstrate how continuous GF interlayers can succeed in arresting...
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...
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....
This study applies the phase-field method for crack behaviors in both layered structure and nacre-like materials to distinguish the importance of the commonly observed toughening mechanisms. First, we investigate the toughening of a simple layered structure, where the surfing boundary condition is ...
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
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...
