Phase Segregation of PEDOT:PSS on Textile to Produce Materials of >10 A mm⁻² Current Carrying Capacity

Abstract

Conductive textiles with exceptional electrical properties have been prepared by coating the conjugated polymer, poly(3,4-ethylenedioxyphiophene)-polystyrenesulfonate(PEDOT-PSS), on polyethylene terephthalate (PET) nonwoven fabrics. Phase segregation from covalent bond formation to surface silica particles generates PEDOT-PSS coated textiles that hold potential for wearable electronics due to the breathability of the fabric, low toxicity, easy processing and lightweight with high current carrying capacity. The conductive textiles were demonstrated for applications such as electrical connections and resistive heating.

Soft Electronically Functional Polymeric Composite Materials for a Flexible and Stretchable Digital Future

“…Electronic textiles were fabricated by coating PEDOT:PSS on fabrics . For example, Otley et al coated PEDOT:PSS on nonwoven polyethylene terephthalate (PET) fabrics, and they found that the PEDOT:PSS/PET fabrics could carry an electrical current of more than 10 A mm −2 . Recently, Xia et al demonstrated flexible silk fibers with high conductivity and high magnetic properties by coating the silk fibers with PEDOT:PSS and magnetic nanoparticles .…”

Tailoring of Durable Conductive and UV-Shielding Properties on Cotton and Polyester Fabrics by PEDOT:PSS Screen-Printing

“…Employment of conductive polymers for the fabrication of flexible and wearable electronics has some advantages over the aforementioned techniques, such as being lightweight, having low processing temperatures, low cost, stretchability, foldability, good adhesion to diverse substrates, and compatibility with various processing techniques [ 6 , 7 ]. Unlike the metals, they do not cause skin irritation and long-term toxicity in direct contact with the skin [ 8 ].…”

“…Moreover, they can be applied on a larger surface area with potential applications for sensors, thermoelectrics, thermocouples, antennae, wearable electronics, and displays such as organic light-emitting diodes (OLEDs), radio frequency identification tags (RFIDs), electromagnetic shielding, high surface area electrodes for capacitors and/or batteries, etc. [ 7 , 8 , 9 ], although they have a remarkably lower conductivity compared to, e.g., electroless copper-plated textiles [ 10 ].…”

Synergetic Effect of Perfluorooctanoic Acid on the Preparation of Poly(3,4‐ethylenedioxythiophene): Lignosulfonate Aqueous Dispersions with High Film Conductivity

“…Since PEDOT:PSS was invented by Bayer AG company in 1994, it has been widely applied as conductive film in organic optoelectronic devices, electrochemical energy conversion and storage devices, biosensors, thermoelectric devices, etc. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] The conductivities of the most widely used Clevios P VP AI 4083 and PH1000 are between 10 À 3 -10 À 4 and 0.2-1 S⋅cm À 1 , respectively. However, owing to the high difficulty in the design and synthesis of polymeric dopants, only a limited amount of PEDOT:PSS alternatives have been reported.…”

“…The most successful polymeric dopant and its corresponding solution processable CP are PSS and PEDOT:PSS, respectively. Since PEDOT:PSS was invented by Bayer AG company in 1994, it has been widely applied as conductive film in organic optoelectronic devices, electrochemical energy conversion and storage devices, biosensors, thermoelectric devices, etc . The conductivities of the most widely used Clevios P VP AI 4083 and PH1000 are between 10 −3 ‐10 −4 and 0.2‐1 S⋅cm −1 , respectively.…”
