“…The area of smart clothes is worth special attention in the context of the applications of the proposed biochar-based fibres. In this field, highly flexible wires are sought that additionally do not exhibit exorbitant electrical requirements [ 33 ]. Additionally, all the composites proposed in the study are based on thermoplastic polymers commonly used in 3D printing technology.…”

Carbon materials are becoming crucial in several industrial sectors. The drawbacks of these materials include their high cost and oil-based essence. In recent years, recycled materials have become possible alternative sources of carbon with several advantages. Firstly, the production of this alternative source of carbon may help to reduce biomass disposal, and secondly, it contributes to CO2 sequestration. The use of carbon derived from recycled materials by a pyrolysis treatment is called biochar. Here, we present composite materials based on different biochar filler contents dispersed in several thermoplastic polymer matrixes. Electrical conductivity and tensile break strength were investigated together with the material characterisation by DTA/TGA, XRD, and scanning electron microscopy (SEM) imaging. Materials with good flexibility and electrical conductivity were obtained. The local ordering in composites resembles both biochar and polymer ordering. The similarity between biochar and carbon nanotubes’ (CNTs) XRD patterns may be observed. As biochar is highly cost-effective, the proposed composites could become a valid substitute for CNT composites in various applications.

“…22 Lepak-Kuc manufactured washable CNT wire by coating with different textile polymers yet suffers deficiency of uniform insulation layer due to irregularities in diameter. 23 He et al designed highly stretchable multiwalled CNT/TPU composite fibers for wearable strain sensors with a strength of only 28 MPa. 24 Thus, the limited tensile strength and abrasion robustness along with controlled diameter and stable electrical performance of CNT yarn still remain a challenge for its real applications in textiles.…”

The advancement of next-generation wearable electronics is highly inclined with electro-conductive yarn having excellent flexibility and functionality. However, the deficiency of existing metal-based and nanomaterial (carbon nanotube, i.e., CNT)-based conductive wires indeed limits their modest requirements due to inadequate elasticity and mediocre antiabrasion ability in conjunction with stable electrothermal performance for enough effective utilization in real textiles. This study introduces an interesting approach to overcome the extant issue by encapsulating CNT yarn with a thin, even shield of textile polymer, i.e., TPU (thermoplastic polyurethane), combining two simple operations of polymer infiltration and twisting. Two different concentrations% of TPU solution (5 and 10%) were selected, and twisted CNT yarn was prepared. Compared to pristine CNT yarn, 5% TPU-CNT yarn possesses brilliantly enhanced tensile strength (+241%), stretchability (+125%), exceptional tensile force (+216%), and extraordinary antiabrasive performance (+1752%). In addition, the good range strain sensitivity (∼39%), stable electromechanical prominence during 28 cyclic loading at 6% tensile strain, and outstanding electrothermal stability (for 200 s) reaching the temperature of 228 °C only within ∼10 s by low driving voltage (2 V) simply represent its high efficacy to satisfy the prerequisite regarding comfort wear and steady conduction for wearable electronics. The potential demonstrations of deicing of ice by CNT/TPU yarn embedded 3D spacer woven composites with 58 times weight ratio within 9.6 min just signify its exceptional E-thermal performance. The wellenough mechanical harmony with schemes and robustness over periodical usages of as-developed highly flexible and sewable TPU-CNT yarn opens up its promising prospects for new-generation smart clothing as well as multifunctional composites.

“…[17][18][19][20] The third technique (such as dip-coating, spray-coating, and drop coating) is creating a coat of conductive materials dispersed in solution, which appears to be an alternative method more suitable for industrialization, [21,22] but requires high solubility and dispersivity of the conductive material to achieve high coating uniformity. A variety of conductive materials including metals (Ag, Au, Cu, and Al), [23][24][25] carbon-based materials (graphene, graphene oxide, and carbon nanotube), [26][27][28] and conductive polymers (polydimethylsiloxane (PDMS), poly (3,4ethylenedioxythiophene):ploy(styrenesulfonate) (PEDOT:PSS), poly(3-hexylthiophene) (P3HT), and polyaniline) [16,29,30] and 2D materials (hexagonal-boron nitride, transition-metal dichalcogenides, and MXenes) [31][32][33] have been adopted for the preparation of conductive textiles. In principle, these materials have traditional and fundamental limits.…”

Colorful Conductive Threads for Wearable Electronics: Transparent Cu–Ag Nanonets

et al. 2022

Electronic textiles have been regarded as the basic building blocks for constructing a new generation of wearable electronics. However, the electronization of textiles often changes their original properties such as color, softness, glossiness, or flexibility. Here a rapid room-temperature fabrication method toward conductive colorful threads and fabrics with Ag-coated Cu (Cu-Ag) nanonets is demonstrated. Cu-Ag core-shell nanowires are produced through a one-pot synthesis followed by electroless deposition. According to the balance of draining and entraining forces, a fast dip-withdraw process in a volatile solution is developed to tightly wrap Cu-Ag nanonets onto the fibers of thread. The modified threads are not only conductive, but they also retain their original features with enhanced mechanical stability and dry-wash durability. Furthermore, various e-textile devices are fabricated such as a fabric heater, touch screen gloves, a wearable real-time temperature sensor, and warm fabrics against infrared thermal dissipation. These high quality and colorful conductive textiles will provide powerful materials for promoting next-generation applications in wearable electronics.
