“…This type of failure can be also due to the slippage of CNT bundles over each other, where relatively weak interactions between the CNT bundles are governed by Vann der Waals forces. Similar kink bands have been observed in tensile testing of CNT yarns in previous publications [16][17] and have been attributed to the compressive stresses. Our SEM images are taken during unloading of yarns and kink bands are observed to form at axial strain levels of 5% and 7%.…”

“…The resulting yarns are in the range of few microns to 100 microns and both the length and diameter of the yarns can be changed by varying the processing parameters [14][15]. Recent studies on CNT based yarns [12,[16][17][18][19] have shown potential as a future in-situ sensor for sensing damage and strain in continuous yarn composites due to its high ductility (i.e. strain to failure is order of magnitude higher than structural yarns) in addition to its high piezoresistivity.…”

“…The major focus of previous research [16][17][18] was to investigate the bulk electromechanical properties of these yarns without consideration of yarn microstructural parameters and deformation modes that affect their sensing capability. The current effort used an advanced test method, which conducts tensile tests in a Scanning Electron Microscope (SEM) to accurately capture the changes in the morphology of CNT yarn as a function of strain applied.…”

“…Even more interesting is the fact that nanoparticle dispersions in a polymer matrix can be rendered macroscopically anisotropic, a feature that has allowed their use in nonlinear optical devices and linear absorbing polarizers, e.g., for display applications [109,110]. …”

Thermoplastic polymers like polyolefins, polyesters, polyamide, and styrene polymers are the most representative commodity plastics thanks to their cost-efficient manufacturing processes, excellent thermomechanical properties and their good environmental compatibility, including easy recycling. In the last few decades much effort has been devoted worldwide to extend the applications of such materials by conferring on them new properties through mixing and blending with different additives. In this latter context, nanocomposites have recently offered new exciting possibilities. This review discusses the successful use of nanostructured dispersed substrates in designing new stimuli-responsive nanocomposites; in particular, it provides an updated description of the synthetic routes to prepare nanostructured systems having the typical properties of thermoplastic polymers (continuous matrix), but showing enhanced optical, conductive, and thermal features dependent on the dispersion topology. The controlled nanodispersion of functional labeled clays, noble metal nanoparticles and carbon nanotubes is here evidenced to play a key role in producing hybrid thermoplastic materials that have been used in the design of devices, such as NLO devices, chemiresistors, temperature and deformation sensors.

“…14,[15][16][17][18][19] To utilize these outstanding properties of SWNTs on a macroscopic scale, considerable efforts have been made to fabricate neat SWNT fibers and SWNT/polymer 3 fibers. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] However, the purification process of SWNTs through the removal of amorphous carbons (ACs) and catalyst particles makes the costs extremely high, which severely hampers their large-scale application. 35 Generally, the catalysts used in SWNT fabrication are transition metals with magnetic properties, such as iron, cobalt and nickel.…”

Magnetic nanocomposite fibers are a topic of intense research due to their potential breakthrough applications such as smart magnetic-field-response devices and electromagnetic interference (EMI) shielding. However, clustering of nanoparticles in a polymer matrix is a recognized challenge for obtaining a property-controllable nanocomposite fiber. Another challenge is that the strength and ductility of the nanocomposite fiber decrease significantly with increased weight loading of magnetic nanoparticles in the fiber. Here, we report high-strength single-walled carbon nanotube (SWNT)/permalloy nanoparticle (PNP)/poly(vinyl alcohol) multifunctional nanocomposite fibers fabricated by wet spinning. The weight loadings of SWNTs and PNPs in the fiber were as high as 12.0 and 38.0%, respectively. The tensile strength of the fiber was as high as 700 MPa, and electrical conductivity reached 96.7 S m(-1). The saturation magnetization (Ms) was as high as 24.8 emu g(-1). The EMI attenuation of a fabric woven from the prepared fiber approached 100% when tested with electromagnetic waves with a frequency higher than 6 GHz. The present study demonstrates that a magnetic-field-response device can be designed using the fabricated multifunctional nanocomposite fiber.
