PEDOT:PSS-Based Conductive Textiles and Their Applications

Abstract

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.

Flexible Antennas: A Review

“…Silver-nanoparticle ink edges over copper nanoparticles due to their low rate of oxide formation [ 21 ]. Very few investigations have been observed for flexible antennas based on copper-based nanoparticles [ 22 ]. Besides nanoparticles, electro-textile materials like Ni/Ag-plated, Flectron (copper-coated nylon fabric), and nonwoven conductive fabrics (NWCFs) are generally used in flexible antennas.…”

PEDOT:PSS/PDMS-Coated Cotton Fabric for Strain and Moisture Sensors

“…In this work, we have added polydimethylsiloxane-b-polyethylene oxide (PDMS) which compensates for the stiffness from PEDOT:PSS. Moreover, we have utilized a different conductive polymer composite of PEDOT:PSS, because of its acceptable electrical conductivity and flexibility [8,9], and PDMS, due to its biocompatibility and extensibility [10]. The result should be a single fabric that senses both strain and moisture.…”

Scalable, All‐Printed Photocapacitor Fibers and Modules based on Metal‐Embedded Flexible Transparent Conductive Electrodes for Self‐Charging Wearable Applications

“…PEDOT:PSS is attractive because of its high optical transparency, electrical conductivity, mechanical durability, electrochemical performance, and compatibility with roll-to-roll (R2R) processing. [15,22] It has been reported that the optoelectronic properties of PEDOT:PSS TCEs can be further enhanced by incorporating Ag metal mesh/stripes, giving rise to better device performance in organic devices, such as OSCs, organic light-emitting diodes, and even SCs. Moreover, the PEDOT:PSS/Ag hybrid TCE can produce more efficient stripe-shaped devices due to the underlying Ag sub-metal electrodes.…”
