Review on PEDOT:PSS-Based Conductive Fabric

Abstract

This article reviews conductive fabrics made with the conductive polymer poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), their fabrication techniques, and their applications. PEDOT:PSS has attracted interest in smart textile technology due to its relatively high electrical conductivity, water dispersibility, ease of manufacturing, environmental stability, and commercial availability. Several methods apply PEDOT:PSS to textiles. They include polymerization of the monomer, coating, dyeing, and printing methods. In addition, several studies have shown the conductivity of fabrics with the addition of PEDOT:PSS. The electrical properties of conductive textiles with a certain sheet resistance can be reduced by several orders of magnitude using PEDOT:PSS and polar solvents as secondary dopants. In addition, several studies have shown that the flexibility and durability of textiles coated with PEDOT:PSS can be improved by creating a composite with other polymers, such as polyurethane, which has high flexibility and extensibility. This improvement is due to the stronger bonding of PEDOT:PSS to the fabrics. Sensors, actuators, antennas, interconnectors, energy harvesting, and storage devices have been developed with PEDOT:PSS-based conductive fabrics.

Electrically Driven Crosslinked Liquid Crystal Polymers†

“…PEDOT:PSS exhibits excellent electrical conductivity, good mechanical flexibility, and high environmental stability, thus rendering it highly desirable for electrically driven LCEs. [89][90] Greco et al [91] developed an electrically driven soft actuator by depositing PEDOT:PSS onto the surface of a nematic LCE. Compared with metallic materials and inorganic nanoparticles, the conductive polymer layer of PEDOT:PSS exhibited a Young's modulus and Poisson's ratio similar to those of the LCE film, thus indicating that it is a better fit for the LCE.…”

Ionic‐electronic coupling in PEO‐PEDOT/potassium triflate composite films for organic mixed conductivity enhancement

“…As previously delineated, composite films based on organic mixed ionic‐electronic conductors (OMIECs) demonstrate a dual effect, encompassing ionic transports facilitated by polyelectrolytes and electronic transport facilitated by conjugated polymers. In the context of this investigation, we present a novel OMIECs‐based composite film comprising PEDOT (Poly(3,4‐ethylenedioxythiophene)) nanoparticles, known for their high electronic conductivity 37,38 in conjunction with complex ions of KOTf (Potassium triflate) 35 integrated into a polyethylene oxide (PEO) film which possesses exceptional ionic transport properties 25,26 …”

Recent Progress in Poly (3,4‐Ethylene Dioxythiophene): Polystyrene Sulfonate Based Composite Materials for Electromagnetic Interference Shielding

“…Among ICPs, PEDOT: PSS is widely used for EMI shielding, because of its properties over other intrinsically conductive polymers such as good stability in the oxidized state, resistance to pH fluctuation, high transparency of its film in visible range, good mechanical and thermal stability, moderate bandgap, and high electrical conductivity. [67,[70][71][72][73] PEDOT is one of the best ICPs to form a percolation conductive network with different types of conductive fillers which will help to further improve the EMI shielding capability. Carbon nanotube, graphene, carbon black and graphene oxide are commonly used as conducting fillers to form percolation conductive network with PEDOT.…”
