Abstract Substantial research efforts are under way to optimize the production of composites enhanced by the incorporation of nanomaterial fillers such as multiwall carbon nanotubes (MWCNTs). It is therefore critical to develop robust methods to detect and characterize MWCNTs in nanocomposites to measure product performance and potential risks from release of the MWCNTs. In this study, the effectiveness of X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and scanning electron microsco...

Abstract Theoretical analysis of the piezoresistive behavior of carbon nanotube (CNT)-based composites is of great importance for understanding the electro-mechanical response of CNT-based composite strain sensors. In this paper, a new and comprehensive analytical model is developed to predict the piezoresistive response of conductive CNT-based composite sensors by considering the effects of CNT aspect ratio, interphase, waviness, dispersion, and so on. Stretching-induced changes in electrical r...

Abstract Polymer composites are widely used in microelectronics and wireless communication, wherein high thermal conductivity and low dielectric loss are highly pursued for efficient heat dissipation and signal transmission. However, improvement of thermal conductivity via combination of thermo-conductive additives usually accompanies with surge of dielectric loss, due to the serious interfacial polarization and phonon scattering, leading to a long-standing blank of thermo-conductive composites ...

ABSTRACT Over millions of years Nature has attained highly optimized structural designs with remarkable toughness, strength, damage resistance and damage tolerance - properties that are so far difficult to combine in artificial high-performance fibre-reinforced polymers (HPFRPs). Recent studies, which have successfully replicated the structures and especially the toughening mechanisms found in flora and fauna, are reviewed in this work. At the core of the manufacturing of damage-tolerant bio-ins...

Abstract In this work, elongational flow supplied by a novel extrusion device, eccentric rotor extruder (ERE), was employed to prepare high-performance poly(L-lactide) (PLA)/poly(e-caprolactone) (PCL) composites. Scanning electron microscopy (SEM) evidenced the elongational flow induced in-situ fiberization, in which the dispersed PCL were stretched into nanofibrils, consequently improved the interfacial adhesion of PLA/PCL. Differential scanning calorimetry (DSC), two-dimensional small-angle X-...

Abstract Polymeric composites with excellent thermal conductivity are in high demand in modern electronics because of their need for efficient heat dissipation. Whereas, the thermally conductive polymeric composites usually be limited by the insufficient effectiveness of the thermally conductive pathway, at the cost of high filler content and deterioration of mechanical strength. At the same time, they lack multi-functionality. Here, we reported advanced thermoresponsive polymeric composites con...

Abstract In the present work tensile, flexural, impact and hardness properties of Prosopis juliflora bark (PJb), Banana fiber (Bf), and Coconut fiber (Cf) reinforced epoxy hybrid bio composites (untreated and alkali treated) are expressed for the first time. This experimental investigation Bf as a base material, PJb and Cf are filler materials. The weight percentage of Bf has been maintained as constant and the remaining two fiber fillers were varied. The untreated composite specimen shows the g...

Abstract At cryogenic temperatures thermoset polymers suffer from low fracture toughness. Herein, we present a strengthening and toughening technique for cryogenic applications using cupric oxide (CuO) nanorods. These nanorods are synthesized via a hydrothermal reaction to give an average length of 1.64 μm and a diameter of 270 nm. They exhibit a low coefficient of thermal expansion (CTE) at cryogenic temperatures, due to the magnetostriction effect. Epoxy nanocomposites containing up to 8 wt% o...

Abstract When sensors are embedded in composites for structural integrity monitoring (SIM), the sensors per se, unfortunately, degrade the original integrity of host composites. Envisaging such deficiency and facilitated by advances in nanotechnology, we develop a new type of ultrathin, piezoresistive sensors using spraying coating and nanocomposites formulated with graphene nanoplatelets/polyvinylpyrrolidone. The sensors are deposited on dielectric membranes made of partially pre-cured B-stage ...

Abstract Liquid metal elastomer composites have gained significant attention in advanced technologies including wearable electronics, soft robotics, and human-computer interactions. This is due to the combination of metallic conductivity and fluidic properties of liquid metal (LM) inclusions in addition to their facile fabrication process. With the emergence of gallium-based liquid metal nanocomposites and advances in synthesis and integration of LM nanoparticles in a variety of polymer matrices...
