Materials possessing exceptional temperature sensitivity and high stretchability are of importance for real-time monitoring on three-dimensional components with complex geometries, when operating under various external deformation modes. Herein, we develop a stretchable sensor consisting cellular graphene/polydimethylsiloxane composite. The first its kind, graphene-based polymer composites desired microstructures produced through direct 3D ink-writing technique. resultant possess...
Cu2+ accelerates the viral-like propagation of α-synuclein fibrils and plays a key role in pathogenesis Parkinson's disease (PD). Therefore, accurate detection is essential for diagnosis PD other neurological diseases. The process impeded by substances that have similar electrochemical properties. In this study, graphdiyne (GDY), new kind carbon allotrope with strong electron-donating ability, was utilized highly selective taking advantage its outstanding adsorption capacity Cu2+. Density...
Abstract Highly stretchable and conductive composites have gained tremendous research interests due to the imperative demands in fields of electronics soft robotics. However, it is challenging maintain original performance under complex external deformations. Here, a one‐step dual‐material 3D printing technique developed rationally assemble liquid metal (LM) into an elastomer lattice. The interconnected deformable network supported by highly ordered robust polydimethylsiloxane lattice...
The immiscible between poly(ε-caprolactone) (PCL) and poly(lactic acid) (PLA) significantly hinders the properties application of blends. In this work, use benzoyl peroxide (BPO) is an effective methods to improve compatibility foamability PCL/PLA tensile test results showed a 41% increase in yield strength 632% elongation at break crosslinked PCL/PLA/0.6%BPO film compared pristine blends, which demonstrate enhancement interfacial interaction. melt blends was gradually increased due...
Poly(butylene adipate-co-terephthalate) (PBAT) is a promising degradable polymer for replacing non-degradable traditional plastics to mitigate pollution. However, its low softening temperature and poor hardness impede application. Herein, PBAT stereocomplex polylactide (sc-PLA) blends were fabricated through melt-blending process balance the heat resistance mechanical strength of in this research. The effects PLA content hot embossing on blend properties comprehensively investigated. results...
Stretchable tactile sensors are popular in soft and conformable electronics, innovations their architectural design manufacturing process demand for more advanced applications. In this work, a resistive-type core-shell sensor was designed fabricated via the coaxial ink writing of continuous single fiber. Particularly, facile tubular deposition modeling method established, which deionized (DI) water selected as core first coextruded with elastomeric shell then scarified replaced by injecting...
This paper provides a method combining eco-friendly supercritical CO2 microcellular foaming and polymer leaching to fabricate small-diameter vascular tissue engineering scaffolds. The relationship between pore morphology mechanical properties, the cytocompatibility, are investigated with respect effects of poly(ε-caprolactone)/poly(ethylene oxide) (PCL/PEO) phase morphologies PEO leaching. When content increases, size decreases density increases. After process, highly interconnected...
The high-strength Mg-7Sn alloys (wt.%) with a heterogeneous grain structure were prepared by low-temperature extrusion (230 °C) the ratio of 9:1 (9E230) and 17:1 (17E230). two extruded contained fine dynamic recrystallization (DRX) grains (FG) coarse unDRX (CG). difference in deformability between CG FG leads to formation structure. average size basal texture intensities increased while volume fraction decreased increasing ratio. Tensile testing results indicated that 17E230 alloy exhibited...
Highly interconnected porous polymer scaffolds were prepared by gas foaming. Poly(ε‐caprolactone)/poly(lactic acid) blends melt mixed and batch foamed using CO 2 as a physical blowing agent. The effects of the foaming temperature, pressure, saturation time on foam morphology related to mechanical properties scaffolds. cell size in cross section decreased became more homogeneous until reached 1.5 hours. With an increase increased markedly uniformity gradually, whereas reverse happened when...
In tissue engineering applications, a scaffold containing an interconnected porous structure is often highly desirable since these pores allow nutrients and signaling molecules to reach all of the cultured cells. this study, microcellular injection molding, mass production method for foamed plastic components, was combined with chemical foaming particulate leaching methods fabricate using poly(ɛ-caprolactone) (PCL). Sodium bicarbonate (SB) employed as agent while carbon dioxide (CO 2 ) used...
