“…Guo et al demonstrated a fabrication of all-organic conductive wires by utilizing patterning techniques such as inkjet printing and sponge stencil to apply PEDOT:PSS onto a nonwoven polyethylene terephthalate (PET) providing a wide range of resistance, i.e., tens of kΩ/sq to less than 2 Ω/sq that allows the resistance to be tailored to a specific application [88]. Sinha et al demonstrated the integration of screen-printed PEDOT:PSS electrocardiography (ECG) circuitry on finished textiles and recorded an ECG signal comparable to Ag/AgCl connected to copper wires [89]. Zhao et al also used screen-printing to produce a PEDOT:PSS and carbon-based disposable electrochemical sensor for sensitive and selective determination of carmine [90].…”

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.

“…Printing technology is considered promising as a postprocessing step to offset the limitation of spinning conductive fibers for weaving and knitting processes. Printing with conductive inks has been used in functional materials for flexible electronics, such as wearable antennas, strain sensors, electrocardiogram sensors, electromyography sensors, and supercapacitors …”

“…Screen printing is widely accepted technique in industry and a number of studies have demonstrated screen printing e‐textiles . Since screen printing requires high‐viscosity inks ranging from 500–5000 mPa s, conductive pastes for screen printing were developed using metal micro/nanoparticles with binding materials, and intrinsically conductive polymers . Even though screen printing is a useful technique for patterning of printed electrically conductive materials on textiles, thick layer deposition (10 1 –10 3 µm) with high viscosity inks negatively alters the textile's historically unique properties such as porosity, flexibility, and fabric hand, all of which are necessary for consumer appeal of textile products …”

In this work, a novel technique of inkjet printing e-textiles with particle free reactive silver inks on knit structures is developed. The inkjet-printed e-textiles are highly conductive, with a sheet resistance of 0.09 Ω sq -1 , by means of controlling the number of print passes, annealing process, and textile structures. It is notable that the inkjet process allows textiles to maintain its inherent properties, including stretchability, flexibility, breathability, and fabric hand after printing process. This is achieved by formation of ultrathin silver layers surrounding individual fibers. The silver layers coated on fibers range from 250 nm to 2.5 µm, maintaining the size of interstices and flexibility of fibers. The annealing process, structure of fibers, and printed layers significantly influence the electrical conductivity of the patterned structures on textiles. Outstanding electrical conductivity and durability are demonstrated by optimizing print passes, controlling textile structures, and incorporating an in situ annealing process. The electrical resistance dependence on the strain rate of the textiles is examined, showing the ability to maintain electrical conductivity to retain light-emitting diode use, stable more than 500 consecutive strain cycles. Most importantly, inkjet-printed e-textiles maintain their characteristic washability, breathability, and fabric hands for applications in wearable technology.

“…Also, the use of a uorosurfactant reportedly improves the wetting properties of PEDOT:PSS solution, which enables the facile deposition of a highly conductive PEDOT:PSS layer on a variety of stretchable substrates. 32,33 The PEDOT:PSS was stirred at high speed (>500 rpm) while various amounts of DMSO were added and blended with the FC-5120. All of the polymer mixtures were ltered through a syringe lter (0.5 mm pore size) aer mixing.…”
