Out-of-plane deformation patterns, such as buckling, wrinkling, scrolling, and folding, formed by multilayer van der Waals materials have recently seen a surge of interest. One crucial parameter governing these deformations is bending rigidity, on which significant controversy still exists despite extensive research for more than decade. Here, we report direct measurements rigidity graphene, molybdenum disulfide (MoS_{2}), hexagonal boron nitride (hBN) based pressurized bubbles. By...
The development of electromagnetic interference (EMI) shielding materials is moving forward towards being lightweight and showing high-performance. Here, we report on silver nanowire (AgNW)/MXene hybrid sponges featuring hierarchical structures that are fabricated by a combination dip-coating unidirectional freeze-drying methods. commercial melamine formaldehyde (MF), designed with buckled structure, chosen as the template for coating AgNW layer (BMF/AgNW). Furthermore, additional irregular...
Direct harvesting of energy from moist air will be a promising route to supply electricity for booming wearable and distributed electronics, with the recent rapid development moisture-enabled generator (MEG). However, easy spatial distortion rigid MEG materials under severe deformation extremely inconveniences human body intense physical activity, seriously hindering desirable applications. Here, an intrinsically stretchable (s-MEG) is developed based on well-fabricated functional ionic gel...
Shape memory polymers (SMPs) that change shapes as designed by external stimuli have become one of the most promising materials actuators, sensors, and deployable devices.
The filtering capacitor plays an essential role in the ever-increasing electronics for current stability complicated environments. However, because of low specific capacitance and bulky volume, devices have difficulty satisfying harsh temperature environment small size supercomputers, electric vehicles, aircraft so on. Therefore, ultra-fast electrochemical is developed on basis vertically oriented graphene iongel electrodes (GI-EC), which demonstrates excellent alternate line-filtering...
Abstract In this study, we report the polymer-based graphene foams through combination of bottom-up assembly and simple triaxially buckled structure design. The resulting not only effectively transfer functional properties graphene, but also exhibit novel negative Poisson’s ratio (NPR) behaviors due to presence structure. Our results show that after introduction structure, improvement in stretchability, toughness, flexibility, energy absorbing ability, hydrophobicity, conductivity,...
Many three-dimensional (3D) nanomaterial-based assemblies need incorporation with elastomers to attain stretchability-that also compromises their pristine advantages for functional applications. Here, we show the design of elastomer-free, highly deformable silver nanowire (AgNW) conductors through dip-coating AgNWs on a 3D polymeric scaffold and following simple triaxial compression approach. The resulting AgNW exhibit good stability resistance under multimodal deformation, such as...
The rapid development of two-dimensional (2D) materials has significantly broadened the scope 2D science in both fundamental scientific interests and emerging technological applications, wherein mechanical properties play an indispensably key role. Nevertheless, particularly challenging is ultrathin nature that makes their manipulations characterizations considerably difficult. Herein, thanks to excellent flexibility vanadium disulfide (VS2) sheets, susceptibility out-of-plane deformation...
The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit application electromagnetic interference (EMI) shielding. In this work, an ordered lamellar structure multiwalled nanotube/Ti3C2Tx (MWCNT/Ti3C2Tx) hybrid films was achieved by vacuum-assisted filtration through hybridization Ti3C2Tx nanosheets nanotubes, where were tightly sticking on surface via physical adsorption hydrogen bonding. Compared with pure films, MWCNT/Ti3C2Tx a significant...
Due to their extraordinary mechanical properties, nanocarbon materials (e.g. carbon nanotube and graphene) are attracting great interests in the field of nanocomposites. One unique feature nanocarbon-based nanocomposites is intrinsically rich interface, allowing them adapt microstructures response external loading and, turn, stiffen themselves. This behavior, called responsive stiffening, was usually observed biological such as bones muscles. The mechanically behaviors particularly exciting...
