Wet Spinning Enabled Advanced PEDOT:PSS Composite Fibers for Smart Devices

Abstract

Poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) is a derivative of polythiophene and an intrinsically conductive polymer (CP). Due to its excellent conductivity, processability, and biocompatibility, it has received widespread attention in the past decade and has become a popular material for wearable electronic devices. Thin films and fibers are the two primary dimensions that PEDOT:PSS has been made into. Compared with two-dimensional (2D) thin films, 1D fibers have natural advantages in integration and structural design, remarkably accelerating practical applications.
