“…It is noted that the linear correlation between fractional resistance and strain for this MWCNT-coated cellulose fiber is up to 18% strain until the final fracture. This linear strain range is much larger than that of CNT-coated natural fiber (about 1.5% strain) [15], CNT/cellulose composite films (7%-13% strain) [16] and other CNT/polymer composites (below 3% strain) [15,19,26]. For our MWCNT-coated cellulose fibers, furthermore, the Rrel value before the final fracture can be up to 200%-400%, which is much higher than that of most reported CNT-based materials.…”

“…where GF is the abbreviation of gauge factor and stands for strain sensitivity, and the parameter, a = ε0 × GF; ε0 refers to the initial strain for the piezoresistivity effect of CNT networks [15,19]. According to the linear correlation in Figure 3a, the GF value for this MWCNT-coated cellulose fiber is 14.5, which is much higher than that of metal alloys used for conventional foil gages (0.74-5.1) [26].…”

“…Thus, these sensory fibers can be woven together with other fibers for smart textiles and wearable technology, for example to be used to monitor the motion of muscles and limbs for rehabilitative and telemedicine applications. Moreover, our MWCNT-coated cellulose fibers can be used as integrated sensors or surface-mounted strain gauges to monitor crack initiation/propagation and strain/stress in different composite structures [15].…”

Smart multi-walled carbon nanotube (MWCNT)-coated cellulose fibers with a unique sensing ability were manufactured by a simple dip coating process. The formation of electrically-conducting MWCNT networks on cellulose mono-and multi-filament fiber surfaces was confirmed by electrical resistance measurements and visualized by scanning electron microscopy. The interaction between MWCNT networks and cellulose fiber was investigated by Raman spectroscopy. The piezoresistivity of these fibers for strain sensing was investigated. The MWCNT-coated cellulose fibers exhibited a unique linear strain-dependent electrical resistance change up to 18% strain, with good reversibility and repeatability. In addition, the sensing behavior of these fibers to volatile molecules (including vapors of methanol, ethanol, acetone, chloroform and tetrahydrofuran) was investigated. The results revealed a rapid response, high sensitivity and good reproducibility for these chemical vapors. Besides, they showed good selectivity to different vapors. It is suggested that the intrinsic physical and chemical features of cellulose fiber, well-formed MWCNT networks and favorable MWCNT-cellulose interaction caused the unique and excellent sensing ability of the MWCNT-coated cellulose fibers, which have the potential to be used as smart materials.

“…Over the investigated temperature range between 10 and 95°C, the electrical resistance (R) of the fiber decreases monotonically as the temperature increases, i.e., the fiber exhibits a negative temperature coefficient, which is also found in other CNTbased materials. 11,21,52 This semiconductor-like behavior of MWCNTs discloses thermal activation of electrons from valence to conduction states separated by a band gap. 50,51 Interestingly, the R exhibits approximately a linear dependence on temperature, with a slope of −0.99 (kOhm°C −1 )( Figure 8a).…”

Electroconductive fibers composed of cellulose and carbon nanotubes (CNTs) were spun using aqueous alkaline/urea solution. The microstructure and physical properties of the resulting fibers were investigated by scanning electron microscopy, Raman microscopy, wide-angle X-ray diffraction, tensile tests, and electrical resistance measurements. We found that these flexible composite fibers have sufficient mechanical properties and good electrical conductivity, with volume resistivities in the range of about 230-1 Ohm cm for 2-8 wt % CNT loading. The multifunctional sensing behavior of these fibers to tensile strain, temperature, environmental humidity, and liquid water was investigated comprehensively. The results show that these novel CNT/cellulose composite fibers have impressive multifunctional sensing abilities and are promising to be used as wearable electronics and for the design of various smart materials.

This review summarizes the recent (from year 2000) advancements in the interphase tailoring of fiber-reinforced polymer composites. The scientific and technological achievements are classified on the basis of the selected strategies distinguishing between i) interphase tailoring via sizing/coating on fibers, ii) creation of hierarchical fibers by nanostructures, iii) fiber surface modifications by polymer deposition and iv) potential effects of matrix modifications on the interphase formation. Special attention was paid to report on efforts dedicated to the creation on (multi)functional interphase in polymer composites. This review is round up by listing current trends in the characterization and modelling of the interphase. In the final outlook, future opportunities and challenges in the engineering of fiber/matrix interphase are summarized.
