“…Hong et al carried out five cycles of in-situ polymerization of PEDOT on poly(trimethylene terephthalate) fabrics in the presence of ferric p-toluenesulfonic acid and ferric chloride as oxidants followed by butane treatment and obtained an electrical conductivity of 3.6 S/cm [79]. Bashir et al reported an electrically conductive polyester fabric with an electrical resistance of~2000 Ω, coated by PEDOT through oxidative vapor phase polymerization (VPP) in the presence of Fe (III) chloride hexahydrate oxidant [80]. They also obtained electro-conductive aramid, viscose and nylon fabrics by the same approach.…”

The conductive polymer complex poly (3,4-ethylene dioxythiophene):polystyrene sulfonate (PEDOT:PSS) is the most explored conductive polymer for conductive textiles applications. Since PEDOT:PSS is readily available in water dispersion form, it is convenient for roll-to-roll processing which is compatible with the current textile processing applications. In this work, we have made a comprehensive review on the PEDOT:PSS-based conductive textiles, methods of application onto textiles and their applications. The conductivity of PEDOT:PSS can be enhanced by several orders of magnitude using processing agents. However, neat PEDOT:PSS lacks flexibility and strechability for wearable electronics applications. One way to improve the mechanical flexibility of conductive polymers is making a composite with commodity polymers such as polyurethane which have high flexibility and stretchability. The conductive polymer composites also increase attachment of the conductive polymer to the textile, thereby increasing durability to washing and mechanical actions. Pure PEDOT:PSS conductive fibers have been produced by solution spinning or electrospinning methods. Application of PEDOT:PSS can be carried out by polymerization of the monomer on the fabric, coating/dyeing and printing methods. PEDOT:PSS-based conductive textiles have been used for the development of sensors, actuators, antenna, interconnections, energy harvesting, and storage devices. In this review, the application methods of PEDOT:SS-based conductive polymers in/on to a textile substrate structure and their application thereof are discussed.

“…Therefore, many efforts have been made over the last decades to develop various textile electronics for wearable human−machine interfaces, biomedical applications, and smart sportswear . In this regard, stretchable and wearable electronic devices in the 1D form, which can be directly integrated into daily clothes without any inconsistency, are greatly promising for future wearable electronics . In addition, the hierarchical property of the fibrous structures (fiber: a small and short piece of a strand, filament: a long strand, yarn: an intertwined 1D structure of fibers or filaments, and fabric: a flexible substance consisting of a network of yarns) makes 1D electronic devices and systems remarkably suitable for advanced wearable electronics.…”

applications, and smart sportswear. [13][14][15][16][17] In this regard, stretchable and wearable electronic devices in the 1D form, which can be directly integrated into daily clothes without any inconsistency, are greatly promising for future wearable electronics. [18][19][20][21][22][23] In addition, the hierarchical property of the fibrous structures (fiber: a small and short piece of a strand, filament: a long strand, yarn: an intertwined 1D structure of fibers or filaments, and fabric: a flexible substance consisting of a network of yarns) makes 1D electronic devices and systems remarkably suitable for advanced wearable electronics. The 1D assemblies including the 1D electronic devices also have unique characteristics appropriate to wearable electronics such as softness, stretchability, breathability, and high tolerance to damage. [3] Stretchability, in particular, is one of the most important properties for practical wearable applications because smart clothes or textiles including such 1D electronic devices should be covered on soft and curved human body. [24] Furthermore, some parts of clothes are frequently stretched and deformed during natural movements in daily life, thereby increasing the importance of stretchability of 1D electronic devices. Although many of existing clothes have achieved certain stretchability with only rigid yarns through specific textile structures such as woven or knitted structures, the stretchability resulting from such textile structures is insufficient to cover high stretchability desired in specific applications. For example, high stretchability of textiles is highly required for sportswear in order to achieve a form-fitting property, high comfortability, and elasticity during exercise. For such purpose, various stretchable yarns such as spandex have been widely used in textile industry. These properties of textiles are also essential for various sensing applications of wearable and textile electronic, resulting that high stretchability should be achieved for the 1D electronic devices. [25,26] In addition, the high stretchability resulting from the use of stretchable conductive yarns can successfully prevent a bagging issue of smart textiles which degrades stability and reproducibility of the smart textiles. For achieving the 1D stretchable electronic devices and systems, the development of 1D stretchable electrodes such as conductive yarns or filaments with high electrical conductivity and stretchability is basically essential above other things. In this regard, recent advances toward developing various high-performance Research on wearable electronic devices that can be directly integrated into daily textiles or clothes has been explosively grown holding great potential for various practical wearable applications. These wearable electronic devices strongly demand 1D electronic devices that are light-weight, weavable, highly flexible, stretchable, and adaptable to comport to frequent deformations during usage in daily life. To this end, the development of 1D electrodes wit...

“…Although the continuous melt-spinning process was used to prepare the PTFE fiber, the fiber showed low mechanical strength compared to typical polymerbased fibers, such as polyethylene terephthalate (PET), polyamide (PA6), and polypropylene (PP). [29][30][31][32] We therefore tried the post-thermal drawing process to not only reduce density but also enhance orientation of the polymer chain, resulting in increased crystallinity and mechanical strength. The thermal drawing was conducted in the stretching zone (between rollers 3 and 4, see Figure 3(a)) at 155 C. We defined the thermal drawing ratio of the PTFE fibers from the speed of the fast (4)/slow (3) roller.…”

Polytetrafluoroethylene (PTFE) has high thermal stability and chemical resistance, and hence is gaining great attention in the industrial field of high-performance filters, membranes, and medical applications. However, since PTFE possesses a narrow gap between melting (330°C) and decomposition temperatures (350°C), the melt-spinning process that is required to satisfy industrial needs for mass production has been limited. Here, perfluoro(propyl vinyl ether) (PPVE) was introduced to decrease the melting point of PTFE then fiber fabrication was performed with the melt-spinning process using a single-screw extruder, enabling the PTFE fiber to fabricate continuously. We selected an optimal melt-spinning condition and obtained PTFE fiber from the melt-processable PTFE/PPVE copolymer. The as-spun PTFE fiber showed low mechanical strength (0.90 g/denier or 89.1 MPa of tenacity). A post-thermal drawing process was performed to increase the mechanical strength of the PTFE as-spun. It demonstrated that the thermally drawn PTFE fiber showed higher mechanical strength (1.84 g/denier or 220.0 MPa of tenacity) due to the increased degree of crystallinity. Also, the other trial, thermal stabilization under N2, suggested as a future modification method to increase mechanical strength further, preventing thermal constriction of the PTFE fiber. The melt-spun and thermally drawn PTFE fibers were knitted and it was confirmed that the fiber has high chemical resistance and similar surface chemistry to conventional PTFE fibers. This study developed a method to enable a melt-processable PTFE fiber fabrication and opens up opportunities for mass production that is crucial in the industrial aspect.
