Graphene fibers have great potential in yarn supercapacitors (YSCs) because of their good strength, flexibility, electrical conductivity, and ultrahigh specific surface area. Among the reported results, graphene fibers show higher capacitance properties, but their mechanical strength is relatively low. Here, we design a simple method to prepare high-performance graphene fibers with high strength and high capacitance by adding carboxymethyl cellulose (CMC) to graphene oxide (GO). The hydrogen bonding network between GO and CMC greatly improves the strength of the fiber. CMC can greatly improve the hydrophilicity of the graphene fiber, reduce the stacking of graphene sheets, increase the effective active area, and thus increase the capacitance. The as-prepared rGO−CMC fiber shows a high strength of 526.4 MPa, and the capacitance of YSCs reaches 197.7 mF/cm 2 .

“…8 Compared with the weaving method for conductive fibers, conductive fabric prepared by the posttreatment process has strong mechanical properties and a long service life. 9,10 The post-treatment process includes carbonizing a fabric surface, metal coating and polymerization of an organic conductive polymer, such as polypyrrole, onto the fabric. 11À13 Polypyrrole is one of the earliest and most widely used conductive polymers.…”

2020

Polypyrrole/polyester-cotton composites were prepared using pyrrole as the monomer, adopting an in situ polymerization on the plain polyester-cotton fabric. The influence of the pyrrole concentration, type and concentration of doping agents on the dielectric properties and conductivity of polypyrrole/polyester-cotton composites were investigated using the method of control variables. The results show that within the frequency range 0.01–1.0 GHz, and for concentrations of pyrrole monomers of 0.3, 0.6, 0.9, 1.2 and 1.5 mol/L, the polypyrrole/polyester-cotton composite had the strongest polarization ability, dissipation ability and absorbing-attenuation ability to electromagnetic waves, and the surface resistance was the smallest and conductivity was the best when the pyrrole concentration was 0.9 mol/L. Within the same frequency range, five doping agents were tested, namely sodium dodecyl benzene sulfonate, p-toluenesulfonic acid, ferric chloride, sodium lignosulfonate and camphor sulfonic acid. The composite with sodium dodecyl benzene sulfonate as the doping agent had the strongest polarization ability, dissipation ability and absorbing-attenuation ability to electromagnetic waves, the lowest surface resistance and the strongest conductivity. Finally, within the same frequency range and using doping agent concentrations of 0.1 and 0.2 mol/L, the composite with doping agent concentration of 0.1 mol/L had the strongest polarization ability, dissipation ability and absorbing-attenuation ability.

Smart textiles represent a revolutionary approach to wearable technology with applications ranging from healthcare to energy harvesting. This review paper explores the importance of textile technologies and highlights their potential to revolutionize consumer electronics. Conventional technologies are sometimes heavy, and lack comfort and flexibility, but smart textiles seamlessly integrate into everyday clothing, improving wearability and user experience. The article emphasizes the need for sustainable sourcing and environmentally friendly production methods, as well as responsible manufacturing and disposal practices. Manufacturing techniques such as wet spinning, melt spinning, electrostatic spinning, weaving, knitting, and printing are detailed and shed light on their role in incorporating electronics into textiles. Several applications of textile‐based devices are being explored, including biochemical sensing, temperature monitoring, energy harvesting, energy storage, and smart displays. Each application demonstrates the versatility and potential of smart textiles in different areas. Despite optimistic progress, challenges remain, from improving energy efficiency to protecting user privacy and data security. The review analyzes these problems and suggests future improvements, including interdisciplinary collaboration to find new solutions. Finally, an overview of the current state of smart textiles provides the future of this technology. It serves as an in‐depth reference for academics and readers interested in understanding recent advances and discoveries in textile technologies, highlighting the importance of this rapidly growing industry.
