Stretchable Conductive Polymers and Composites Based on PEDOT and PEDOT:PSS

Advanced Materials, Journal Year: 2019, Volume and Issue: 31(10)

Published: Jan. 2, 2019

Abstract The conductive polymer poly(3,4‐ethylenedioxythiophene) (PEDOT), and especially its complex with poly(styrene sulfonate) (PEDOT:PSS), is perhaps the most well‐known example of an organic conductor. It highly conductive, largely transmissive to light, processible in water, flexible. Much recent work on this ubiquitous material has been devoted increasing deformability beyond flexibility—a characteristic possessed by any that sufficiently thin—toward stretchability, a requires engineering structure at molecular‐ or nanoscale. Stretchability enabling range applications envisioned for PEDOT energy healthcare, such as wearable, implantable, large‐area electronic devices. High degrees mechanical allow intimate contact biological tissues solution‐processable printing techniques (e.g., roll‐to‐roll printing). PEDOT:PSS, however, only stretchable up around 10%. Here, strategies have reported enhance stretchability polymers composites based PEDOT:PSS are highlighted. These include blending plasticizers polymers, deposition elastomers, formation fibers gels, use intrinsically scaffolds polymerization PEDOT.
