Abstract null null New target applications for microfluidic devices have been focused on home usability, wearability and cost-effectiveness. Towards these goals, in this work, a controllable, bendable, and all‑organic, nozzle‑diffuser microfluidic pump was designed, fabricated and tested. First, to resolve the crucial issue of high driving voltage, the ferroelectric polymer poly(vinylidene fluoride‑trifluoroethylene) (P(VDF‑TrFE)) was optimized by adding core‑shell structured Al2O3@CNT nanofille...

Although the ultra-large induced strain of ferroelectric polymers has been achieved under an electric field near breakdown strength, the high driving voltage has been a long-standing obstacle for their safety applications in the actuator, transducer, wearable devices. To resolve this issue, novel core–shell structured CNT–Al2O3 nanoparticles grown via atomic layer deposition are utilized to improve the electromechanical properties of P(VDF-TrFE)-based nanocomposites under low applied fields. The...

Abstract In this paper, a series of pull-out simulations of graphene are carried out to investigate the influence of two-dimensional (2D) geometric shapes of graphene nanosheet on the interfacial load transfer in graphene/PMMA nanocomposites by means of molecular dynamics (MD) simulation. Three common types of shapes, i.e. rectangle, trapezoid and sawtooth, are considered. It is found that the drastically improved pull-out force and interfacial shear strength is highly dependent on the 2D geomet...

Abstract 3D printing of arbitrary shapes and unique architectures offers unparalleled flexibility and simplicity for fabrication of highly complex 3D conformal electronics. It drives up high demands in electronic materials with excellent processability and functionality simultaneously. Herein, we overcome this challenge in prepared nanofiller/polymer piezoelectric composite by incorporating ultralow loadings (0.2 wt%) of boron nitride nanotubes (BNNTs) in photocurable polymer solution. Furthermo...

Abstract Reducing the operating voltage of dielectric elastomer actuator (DEA) without compromising breakdown strength (Eb) and elasticity has been one of the grand challenges to its practical application in various fields, such as the wearble devices. In this study, novel dielectric elastomers offering intrinsically good integrated performances are achieved by introducing CNT-Al2O3 core-shell nanostructures to form various nanocomposites. Dielectric constants (er) of these nanocomposites show a...

Molecular dynamics (MD) simulations of the titanium-graphene nanocomposites (TiGNCs) under uniaxial tension are carried out to investigate the mechanical properties and reinforcement mechanism of graphene in composites. It is found that introduction of mechanically robust graphene limits the strain-induced dislocation and amorphization and thereby highly improves the mechanical properties of metallic titanium that are greatly affected by the crystal stacking orientation of graphene and titanium ...

Under the combination of the passive adhesion generated by micro/nano-structures on their feet and the active mechanical stimulus of their toe muscles, geckos can stably walk on vertical walls and horizontal ceilings. Inspired by such stimuli-responsive systems in nature, an active adhesive soft gripper stimulated by low voltage (usually ≤ 6 V), consisting of a passive mushroom-like adhesive structure and an electrically-active liquid crystal elastomer working as toe muscle, is proposed in this ...

Ensuring material performance reliability and lifetime is crucial for practical operations. Small cracks on the material surface are often detrimental to its safe operation. This study describes the development of a hydrogen bond-rich puncture-resistant polyurethane elastomer with supertoughness. The as-prepared polyurethane transparent films feature high tensile break strength (57.4 MPa) and great toughness (228 MJ m-3). Additionally, a facile, low-cost, crack self-diagnostic approach through p...
