Summary: We invented a feeding wire device and combined it with the drawing device of the spinning frame to accurately position the wire in the middle of the core yarn. This solves the problem of wire exposure on the fabric surface. We used degradable and environmentally friendly modal as roving, Cu and SS as conductive yarns, and explored the effects of shielding networks, lamination layer number, lamination angle, and number of metallic wires. Conductive woven fabrics with a lamination angle of 0 degrees and both warp and weft yarns composed of conductive core yarns can build a complete conductive network. The average EMI SE of single-layered conductive woven fabrics is 30 dB.
When only the weft yarn is composed of a conductive yarn, various lamination angles and layers significantly improve the EMI SE of the conductive woven fabrics. However, the shielding value of the two metal fabrics is not a multiple of the single metal fabric. Increasing the lamination layers increases the fabric thickness and reduces gas permeability and SSE/t value.

Summary: In this work, a conductive TEMPO-cellulose nanofibers (TONF)/conductive carbon black (CCB)/ Vinasse activated carbon (VAC) (TCA) composite was constructed by electrostatic adsorption, freeze-drying, and hot pressing. The assembled supercapacitor exhibits a high specific capacitance of 263F g-1 (672 mF cm-2), energy density of 23.8 Wh kg 1, and power density of 5.7 KW kg 1. An intelligent electromagnetic (EMI) shielding TCA-V composite material with shape memory function was also prepared. These remarkable features make nano cellulose/carbon-matrix composites have great attraction and potential in the field of supercapacitors and intelligent EMI shielding.

Summary: This study proposes an effective strategy for developing conductive fabrics by constructing a composite of carbon nanotube (CNT)/Ti3C2Tx MXene/polyaniline (PANI)/liquid metal (LM), which improves the performance of electromagnetic interference (EMI) shielding and Joule heating. The conductive fabrics decorated with CNT/Ti3C2Tx/PANI/LM exhibit high EMI shielding efficiency and absorbing shielding effectiveness, outperforming pristine MXene film and pure CNT layer. The EMI shielding performance can be further enhanced when three layers of conductive fabrics are combined. Additionally, the conductive textiles demonstrate excellent Joule heating performance. The combination of these components provides lightweight, flexible, and multifunctional conductive textiles with superior EMI shielding and efficient Joule heating capability, making them highly desirable for various applications.

Summary: This study developed highly conductive fabrics for electromagnetic interference (EMI) shielding by dip-coating conventional cotton and linen fabrics in Ti3C2Tx MXene dyes, showing significant EMI shielding effectiveness compared to commercial metal-based conductive fabrics. The EMI shielding effectiveness of the fabrics increased with the number of dip-coating cycles and remained stable even after two years of storage under ambient conditions.

Summary: This study proposes a netting and anchoring strategy for high-performance stretchable electronics. By adding a small amount of polyborosiloxane (PBS) prepolymer, the formed PBS networks can both physically entangle with the PDMS networks and anchor them to adherent surfaces with reversible bonds. The obtained composites exhibit high adhesion strength and conductivity due to good wettability, uniform interfacial bonding, and stress transfer for energy dissipation.

Summary: The doped polyaniline mixed with divinylbenzene as a crosslinking thermoset polymer has demonstrated to be an effective structural EMI shielding material, achieving maximum SE values at X-band frequencies with a 1 mm thickness. The primary shielding mechanism of this material is absorption due to its high conductivity, with dielectric constant and permeability estimated to understand the shielding mechanisms. Additionally, a conductive layer based on PANI has been successfully applied to fiber-reinforced composites for self-EMI shielding applications, achieving high SE values for both GFRP and CFRP composites with a 1 mm thickness.

Summary: This study investigates the effect of spatial distribution of silver nanowires (AgNWs) on the electromagnetic interference (EMI) shielding performance of materials. The results show that dip-coated samples with three-dimensional (3D) AgNW networks outperform spray-coated samples with two-dimensional (2D) AgNW layers in terms of EMI shielding effectiveness (SE). Higher concentration of AgNW dispersion leads to more excellent EMI shielding performance, with dip-coating showing a specific SE of 6.62 x 10(4) dBcm(2)/g at 0.5 wt% AgNW dispersion.

Summary: In this study, the modulation of coating structure was systematically studied to investigate its effects on the electromagnetic shielding performance. It was found that increasing the amount of interfaces in the coating can significantly enhance the shielding effectiveness of the coated fabric. The presence of more GO/PPy interfaces in the coating leads to a stronger electromagnetic shielding enhancement, providing guidance for the rational design of high-performance EMI shielding materials.
