“…Additionally, the TEM images show that AgNPs in the AgNPs/GO composite are relatively evenly spread (Figure c), whereas an amorphous layer is observed on the edges of AgNWs in AgNWs/GO-SH, likely attributed to the adsorption of PVP on the crystal surface of AgNWs (Figure d). The synthesized AgNWs exhibit a distinctive array of crystal facets aligned parallel to the nanowire stretching direction, with a facet spacing of 0.25 nm (Figure e), consistent with the silver (111) facet spacing as indicated by the XRD results …”

“…The synthesized AgNWs exhibit a distinctive array of crystal facets aligned parallel to the nanowire stretching direction, with a facet spacing of 0.25 nm (Figure 3e), consistent with the silver (111) facet spacing as indicated by the XRD results. 31 In the analysis of the physical phase structure of the prepared AgNWs, XRD analysis revealed the presence of four diffraction peaks, namely (111), ( 200), (220), and (311), with corresponding diffraction angles 2θ of 38.11°, 44.30°, 64.45°, and 77.40°, as depicted in Figure 4a. These diffraction peaks align perfectly with those of silver crystals possessing a facecentered cubic structure (JCPDF No.…”

The electrical conductivity can be significantly improved by constructing a three-dimensional conductive network through the chemical bonding of highly conductive one-dimensional AgNWs with two-dimensional GO. To achieve this, under acidic conditions and catalytic action at temperatures, the carboxyl group of mercaptoacetic acid undergoes esterification reaction with the hydroxyl group on GO. This reaction introduces a sulfhydryl group onto the surface of GO, resulting in the formation of graphene oxide bearing a sulfhydryl group, denoted as GO-SH. Subsequently, these sulfhydryl groups serve as growth sites for silver crystal species, allowing for precise control over the distribution and arrangement of AgNWs. The oriented arrangement of AgNWs enabled the successful preparation of AgNWs/ GO-SH composites with high electrical conductivity. Following this, the composites underwent comprehensive analysis of their structure and morphology using various characterization tools. The composite coatings prepared by vacuum filtration and mechanical pressing exhibited excellent electrical conductivity (2275.4 S/cm), as well as superior electromagnetic shielding properties (SE, 65.23 dB). These findings suggest promising applications in the field of electromagnetic shielding.

“…On another cotton fabric, Zing et al fabricated a flexible silver nanowire/cotton fabric that was highly sensitive to temperature by using agents including caffeic acid and polyvinypyrrolidone at room temperature, as shown in Fig. 7 b [ 140 ]. The composite showed a good EMI SE of 38.2 dB in the X band with a thickness of 0.225 mm.…”

Continuous monitoring of physiological health status and effective protection against external hazards is an indispensable aspect of healthcare management for critically vulnerable populations, particularly for infants or babies. So, the exploration of all-in-one devices remains critical to avoiding their injury and illness. The integration of multiple properties such as sensing, electromagnetic protection, warming/cooling, and water/ bacterial repellence into a common fabric is no doubt a promising solution to coping with diverse application scenarios. However, achieving simultaneous integration in an effective and durable fashion faces huge challenges. Herein, multifunctional fabric was achieved by sequentially coating MXene, carbon nanotubes (CNTs), and self-healing polyurethane (PU) onto cotton fabric. The outstanding conductivity of MXene and CNTs as well as the self-healing ability of PU synergistically enable a flexible, breathable, protective, and sensing fabric with a good durability. It could detect the body motions like bending of the finger, elbow, wrist, and knee, with a high gauge factor of 8.78 and fast response. Moreover, this sensing fabric could protect the wearers against electromagnetic waves and bacteria, delivering a minimum reflection loss of −57.6 dB at 7.6 GHz and high bacterial inhibition efficiency due to the incorporation of MXene and polyethylenimine. Besides, the electrothermal performance of carbonaceous materials enables them to act as a heater for body warmth. The synergistic design of this multifunctional textile offers a promising strategy for producing advanced smart textiles, holding great promise in infant or baby healthcare.
