Conductive polymers are flexible, lightweight, and low cost suitable for a smart textile which is one of the key devices for wearable electronics. Recently, the water soluble self-doped poly(3,4-ethylenedioxythiophene) (S-PEDOT) in which the sulfonic acid group was introduced into the side chain of PEDOT was synthesized. It was found that electrical conductivity of the S-PEDOT microfibers attained as high as 1815 S/cm. In this study, fabrication of highly conductive microfibers was investigated by optimizing the wet-spinning conditions.
