“…This increased electrical conductivity of the WPrGO hybrid fibre than that of the CPrGO fibre further confirmed the efficient bonding of the amino groups of wool with the hydroxyl and carboxylic groups of the GO sheets as shown by chemical analysis (FTIR). Additionally, due to having higher polar nature, the amide groups can easily be bonded with hydrogen or accept hydrogen on both sides of its structure, which helps the enhancement of the electrical conductivity of the WPrGO hybrid fibres 4 , 9 . Compared to other chemical reduction processes, the use of hydrazine hydrate as a reducing agent increases the electrical conductivity of the material 51 .…”

This work aims to evaluate the potential of using textile waste in smart textile applications in the form of a hybrid fibre with electrical properties. The bio-based electrically conductive fibres were fabricated from waste wool and polyacrylonitrile (PAN) via wet spinning with different wool content. The control PAN and hybrid fibre produced with the highest amount of wool content (25% w/v) were coated with graphene oxide (GO) using the "brushing and drying" technique. The GO nanosheets coated control PAN and wool/PAN hybrid fibres were chemically reduced through hydrazine vapour exposure. The Fourier transform infrared spectroscopy showed the presence of both protein and nitrile peaks in the wool/PAN hybrid fibres, although the amide I and amide A groups had disappeared, due to the dissolution of wool. The morphological and structural analysis revealed effective coating and reduction of the fibres through GO nanosheets and hydrazine, respectively. The hybrid fibre showed higher electrical conductivity (~ 180 S/cm) compared to the control PAN fibres (~ 95 S/cm), confirming an effective bonding between the hydroxyl and carboxylic groups of the GO sheets and the amino groups of wool evidenced by chemical analysis. Hence, the graphene oxide incorporated wool/PAN hybrid fibres may provide a promising solution for eco-friendly smart textile applications.

“…Of previously reported conductive inks, nanocarbon-based conductive inks, such as carbon black, 14 carbon nanotubes 15,16 and graphene, 17,18 have great chemical stability, conductivity and environmental friendliness, and much interest is being paid to them. Among nanocarbon materials, carbon nanotubes are regarded as the most promising active material for FEs, because carbon nanotubes with a high aspect ratio (>500) easily form interconnected conductive networks on the porous and rough surface of fabric.…”

Carbon nanotubes have been widely used to formulate printed conductive ink in recent years due to their excellent conductivity, chemical stability and mechanical properties. However, the common problems of this ink, such as poor adhesion and low resistance stability under large deformation, hinder its application in the fabric electrodes (FEs) of wearable and stretchable e-textiles. Herein, conductive inks with a simple preparation process, high adhesion and conductive stability were formulated by mixing the conductive filler, multi-walled carbon nanotubes (MWCNTs), into a thermoplastic polyurethane matrix with a reversible cross-linked structure. Then it is evaluated whether the MWCNT-based conductive ink is suitable for the screen-printing fabrication of highly durable and washable FEs. The experimental results showed that the screen-printed fabric electrode exhibited remarkable resistance stability under bending and folding deformation. In particular, after 1000 bending cycles and 100 folding–unfolding cycles under additional pressure, the sheet resistance of FEs only increased by 0.8% and 5.0%, respectively. Moreover, the screen-printed conductive pattern has strong adhesion to polyamide fabric substrate by the Scotch tape and washing tests, and there are no significant changes in resistance and surface morphology. High-performance conductive inks with facile and large-scale production potential are developed, and show great prospect in the development of wearable printing e-textiles.

of detecting various physiological signals and motions. They are integrated into or attached to apparel via knitting, [2] embroidery, [3] and pasting [4] to provide a longterm and stable detection of tiny to large deformations without sacrificing comfort and freedom of motion, and thus have great potential in personal health care, [5] sports, [6] rehabilitation, [7] robotics, [8,9] etc. Textile strain sensors are stretchable and sensitive to tiny deformations. Integrating them into apparel while avoiding deformation to maintain sensor accuracy is crucial for practical applications. A textile strain sensor that can be seamlessly integrated into apparel under precise tension is desired.Textile strain sensors are categorized as resistive, [10] capacitive, [11] piezoelectric, [12] triboelectric, [13] and optical. [14] Resistivity is the most adopted strategy due to its facile fabrication and use. [15] The key to developing textile resistive strain sensors is to choose the right materials, assembled structures, and fabrication methods. [16] Textile resistive strain sensors typically consist of conductive materials and stretchable supporting substrates. [17] The conductive materials include carbon nanotubes (CNTs), [18,19] reduced graphene oxide (rGO), [4,8,20] carbon black (CB), [21] conductive polymers (e.g., polypyrrole (PPY), poly(3,4-ethylenedioxythiop hene):poly(styrenesulfonate) (PEDOT:PSS)), [22,23] metal nanoparticles and nanowires. [24,25] The stretchable supporting materials are normally Ecoflex, [26] polydimethylsiloxane (PDMS), [24] polyurethane (PU), [8,18,27] and rubber. [28] Textile resistive strain sensors detect strains by contacting and separating conductive particles, fibers, or yarns to adjust the resistivity. The principles include geometrical transformations, changes in the conductive network, and the formation of cracks or wrinkle microstructures. [29] Textile resistive strain sensors are evaluated in terms of gauge factor (GF), reliable strain range, and stretching cycles. [29] Textile conductivity can be realized in all three textile processes, i.e., fiber spinning, yarn spinning or covering, and fabric forming. Current textile strain sensors are linear, planar, or three-dimensional (3D), among which 3D fabric strain sensors are thicker and heavier, and are hard to integrate into apparel to achieve wearing comfort. [11,30,31] Linear resistive strain sensors are based on conductive fibers or yarns, manufactured by using liquid metal (LM) injection, [32,33] melt-spinning, [34] wet-spinning, [18,23,25] coating techniques, [10,19,20,26,[35][36][37] twisting Textile strain sensors capable of monitoring human physiological signals and activities have great potential in health monitoring and sports. Integrating them into apparel to be wearable, repeatable, and sensitive remains a great challenge, impeding their practical applications. This paper reports a fabric strain sensor that can be seamlessly integrated into various apparel under precise tension through industrial-scale production. A conductive...
